Vienna, the “Most Livable City” in the World, is now taking a step forward in its tourism and hospitality sectors, with hotels like Citadines Danube leading the way. 

The recently held Hotel Investment Conference CEE (HOTCO) 2025 in Vienna, Austria, featured the core theme “How to Make Money in the Hotel Industry?” 

Furthermore, the conference, held on January 20th and 21st, 2025, discussed emerging trends in tourism and hospitality in Austria and other European countries. 

Now, the impeccable hospitality of Vienna is one of the key reasons behind Austria’s record-breaking 2023 records. The country had 115.6 million overnight stays in the same year. 

But how will the hospitality industry consolidate or boost its success? What are the major trends the best hotels in Vienna are going to adopt soon?

Let’s discuss this in this Tour and Travel Blog.

The Best Hotels In Vienna: Blending Sustainable Practices With The Best Technology

The Best Hotels In Vienna_ Blending Sustainable Practices With The Best Technology

What makes Austrian hospitality so special? The country and its capital, Vienna, have successfully blended tradition with sustainability and cutting-edge technology. 

On one hand, the best hotels in Vienna are incorporating big data and AI into their systems. On the other hand, the hotels in the Austrian capital are improving the quality of hospitality and tourism with sustainable practices. 

How Are The Best Hotels In Vienna Heading Toward An AI-Driven Future?

How _Are The Best Hotels In Vienna Heading Toward An AI-Driven Future_

From tailoring guest preferences to helping guests with queries, AI is set to help the best hotels in Vienna achieve the most streamlined operations. 

1. Understanding Guest Preferences For A Tailored Experience 

While traveling to a place, we now look for an experience that is meaningful to us. That is why personalization is the key these days. 

Additionally, travel preferences and requirements vary for each traveler. 

For example, if you are traveling solo to Vienna, your criteria for choosing an accommodation will be different from those for choosing a hotel when traveling to Vienna with family. 

Today, hotels in Vienna are utilizing big data and AI to understand the type of experience a guest desires. 

Moreover, AI algorithms that predict guest requirements help improve repeat stays. It works like the 20-year staff member in a hotel who knows everything about the regular visitors.   

Additionally, sentiment analysis is combined with AI analytics and natural language processing (NLP) to enhance the guest experience. 

2. Chatbots And Virtual Assistants Helping Guests With Queries And Tasks

Do you have a query? Do you need guidance on certain things? You can ask an AI chatbot or virtual assistant to help you in the following cases. 

  • Asking for Wi-Fi passwords
  • Scheduling calls
  • Interacting with you about the things they want

Now, some of the best hotels in Vienna are also utilizing chatbots with distinct personas to establish favorable connections. 

To make these virtual assistants feel more natural and engaging, many hotels are now exploring text to speech technology, which allows chatbots to respond with lifelike voices instead of just on‑screen text.

3. Smart Kiosks And Mobile Apps With AI Automating Guest Check-in

You need to check into a hotel in Vienna. There is a smart kiosk in the reception, or you can use an AI-enabled app to verify your identity, obtain your room keys, or even unlock an electronic key and head to your room in minutes. 

This is amazing, as you don’t need to stand in a queue or waste your time checking in.

4. Better Hygiene With Automated Cleaning Schedule And Robot Cleaners 

The best hotels in Vienna can now use AI to automate their cleaning schedules. AI will take care of it when you have checked in or checked out, and at the interval of cleaning your room and other facilities. 

AI can also help schedule cleaning in your room based on the preferences you shared at check-in. 

Moreover, as part of optimized resource management, AI can reduce or eliminate the need for human intervention in the cleaning task. 

Hotels can now utilize scrubbing robots programmed to clean according to schedules set based on traffic or footfall in specific areas.

5. Enhanced Security With AI Incorporation In Surveillance

AI-enabled surveillance systems can read and assess camera images, footage, and data provided by the smart access system. 

AI can also analyze crowd behavior to identify any security threats in the hotel. Thus, AI can minimize or reduce the risks of unlawful or disruptive activities in hotels. 

So, the surveillance system becomes stronger with the integration of AI, and the process also becomes cost-effective. With AI, you don’t need human staffing to monitor cameras or access system feeds.

6. Impeccable Upkeep With Maintenance Prediction

AI with “predictive maintenance algorithms” can monitor the health and functions of all the following setups and infrastructure. 

  • HVAC Machines
  • Elevators
  • Lighting Setups
  • Vehicle Fleets

The algorithm will also help make the ideal maintenance schedule to keep all the facilities in working condition. 

This minimizes the risk of major breakdowns.

7. The Best Hotels In Vienna Are Building A Sustainable Future

Vienna is now the newest member of the International Network of Sustainable Tourism Observatories (INSTO). 

As a member of INSTO, Vienna will now monitor the social, economic, and environmental impact of tourism.

Through the Sustainable Tourism Observatory, Vienna fosters dialogue, innovation and collective stewardship to co-create sustainable destination development, ensuring tourism enhances the quality of life for all, while preserving Vienna’s unique cultural and natural resources.
Norbert Kettner, CEO, Vienna Tourist Board

This membership of ISRO also demonstrates the city’s commitment to establishing its leadership in sustainability. It is also a great step forward toward executing the ambitious “Smart Climate City Strategy.”

The best hotels in Vienna also adhere to the city’s strong commitment to sustainability. 

The use of water-saving fixtures, rainwater harvesting, energy-efficient setups, and unconventional energy resources is among the major sustainable practices that hotels in Vienna are adopting today. 

Additionally, there is a strong emphasis on waste reduction and management. Composting and recycling are two important elements of sustainable waste management. 

Additionally, sourcing food and essentials from local vendors is a great way to support local communities and reduce transportation-related emissions.

Best Hotels In Vienna: Bring AI And Sustainability Together 

AI can help the best hotels in Vienna implement the best sustainable practices through Smart energy reduction and smart energy management systems. 

Thus, hotels can reduce their energy consumption, lower utility bills, decrease water consumption, and decrease their carbon footprint. 

So, visit the hotels in Vienna and see how the best accommodations in the Most Livable City of the World offer you the most meaningful experience.

Australia’s Best-Kept Secret: Tailored Travel Experiences In The High Country

BY  Sibashree Sep 4, 2025

Let’s be real, Victoria’s High Country is one of those spots that feels kind of hidden, like it’s been waiting for someone to stumble in and go “Whoa, how did I not know about this place?”  Seriously, tucked up in the northeast, you get these rolling vineyards, pointy mountain tops, and small towns with old brick buildings that seem frozen in some movie scene.  There’s room to breathe here—like, actual space where you don’t find thirty strangers photobombing your sunset shot.  It’s slow, in the best way. Want to go wine tasting, hike, or just kick back by a crackling fire? Sorted.  No crowds, no stress. It’s basically paint-your-own-adventure, but with better cheese. So, if you are looking for some of the best-secret travel experiences in Australia, I have got you covered. In this blog, I am going to bring together all the hidden gems around Australia. Helping you to choose your next vacay spot. So, keep reading to know more! Why Australia Is Popular Among Tourists? Generally, Australia comes with its incredible stretch of natural destinations covering pristine waters, long beaches, coral reefs, and more. So, basically, offering a single vacation spot for all kinds of tourists. Whether you love beaches or mountains, in Australia, you’ll find the best place to enjoy. Moreover, it attracts worldwide tourists for its unique wildlife— koalas, platypuses, kangaroos, capybara, and many more. In addition to this, it has the perfect balance of compelling cityscapes with iconic landmarks like the Sydney Opera House and natural places like the Ayers Rock. Naturally, the famous tourist areas remain crowded throughout the year. Why The High Country Is Australia’s Best-Kept Secret? Magic? Yeah, kind of—if magic means huge open skies, rivers you’re tempted to splash in, vineyards everywhere, and little towns like snapshots from a hundred years ago.  You take a walk, and it’s weirdly quiet (the good kind). Unlike beach spots where everyone and their dog shows up, here it’s calmer per minute.  Moreover, think summer meadows exploding with wildflowers, autumn leaves that look like pure gold, winter with that snowy hat on the mountains, and spring… well, green everywhere.  You get the idea. Honestly, it’s almost like the scenery is trying to show off.  Moreover, it doesn’t matter if you’re the cultural sort, a view-chaser, or a fan of silence—this place just adapts to whatever mood you drag in. No two trips end up feeling the same. The Appeal Of Tailored Travel Experiences In Australia’s High Country Here’s the fun part: you don’t have to follow anyone’s checklist. High Country feels custom-built for daydreamers and doers.  You could do a private wine tour (some of these tiny wineries? Absolute legends), wander through hills on a route a friendly local mapped out just for you. Moreover, have a chef show up at your rental to cook dinner while you argue about whether altitude affects your appetite.  These “tailored” experiences aren’t marketing fluff—they’re real.  People actually talk to you, swap stories, offer shortcuts to the best lookout or bakery, stuff that isn’t in guidebooks.  Your sunrise—just yours. A roaring fire after dark, maybe with wonky marshmallows. Everything feels a little personal, even the random bits. Best-Secret Travel Experiences In Australia Unlike the common belief, the best secret travel spots in Australia offer a more tranquil and exquisite experience.  So, if you want to explore a new place without rushing through the crowds, here are the best travel experiences in Australia to try— 1. Curated Outdoor Adventures Not the outdoorsy type? Eh, don’t worry—you might still find yourself hiking and loving it here.  There’s so much: chill river walks, wildflower chasing, the classic “get lost then get found” moments.  Moreover, cycle on country roads (watch for surprise sheep), or try horseback riding across wide open spaces where your phone signal dies and your smile doesn’t.  In the cold season, get ready for ski slopes, snowboard runs, maybe a snowball fight if you’re feeling childish.  Warm months? Kayaks, lazy fishing, lakes that invite you to nap on a picnic blanket.  Moreover, you don’t have to go all-out—there’s always someone happy to point you to a gentle trail if, like me, you still haven’t recovered from yesterday’s bike ride. 2. Boutique Stays & Accommodation Gems Here’s where the High Country goes next-level.  Also, you’ve got heritage cottages with lumpy but lovable beds, eco-retreats shadowed by gum trees, and boutique lodges that scream “retreat” in a way big hotels literally never do.  Every spot has this mad personal touch—maybe cookies baked by your host, or a recommendation for tomorrow’s adventure scribbled on a napkin.  Privacy? Tons of it, plus character in bucketloads.  Moreover, hosts here treat visitors like friends on holiday, sometimes even inviting you to join a barbecue with neighbours.  It’s everything big chains try (and fail) to fake. You don’t just stay—you belong, for a little while. 3. Culinary & Cultural Delights Hungry? Good, because High Country food honestly deserves its own chapter. You’ll be sipping wine at vineyards run by folks who might let slip their secret grape nicknames.  Moreover, meals come farm-to-table, straight-up local: think bread still warm, cheese so creamy you’ll wonder if you’ve tasted the real deal before. And the markets—buzzy and brimming with jams, loaves, and pastries. But there’s more than just eating. Moreover, heritage towns, pocket-size galleries with art that makes you squint and nod, and festivals where the party just keeps rolling.  You may accidentally join a winemaker’s gossip session, or get pulled into a debate over which honey is “actually best.” It’s a low-pressure, high-reward scene. Your High Country, Your Way No matter how many photos you take from your travel experiences in Australia, you’ll still leave with details stuck in your head. Maybe it’s the view at dusk, the weird bird you saw on the rail trail, or the taste of a random pastry so good you bought three more for the car ride home.  Adventures? Up to you. Chilled days just watching the fire? Totally fine.  Moreover, this place shapes itself around your vibe, not the other way round. Relaxed, wild, somewhere in-between—the High Country delivers.  Go ahead, plan your escape, and make sure to leave at least one day unscheduled for whatever surprise catches you. It’s good like that.

How Can You Avoid Travel Stress? Is Travel Anxiety Normal?

BY  Sibashree Sep 8, 2025

Yes, travel anxiety is normal. From a family trip to a business trip, travel anxiety happens. Being a traveler and travel blog editor, it still happens to me!  Also, the other day, I was reading a report on Newsweek about how Gen Z travelers on business trips feel super anxious. The report says,  “A new survey conducted by Ipsos U.K. and commissioned by American Express Global Business Travel (Amex GBT) found that while 70 percent of Gen Z employees aged 18 to 28 look forward to traveling for work, more than half called the experience stressful.” Nevertheless, referring to where I started, every kind of trip can be stressful, especially if you are like me, who has to take care of the itinerary, all the bookings, and other stuff. I, in fact, feel more stressed before traveling with my family, as for business travels, there is at least some assistance from my office.  So, for everyone, traveling is not as romantic as you may feel it is. Just the thought of being in a foreign location and not knowing anything—or knowing anyone—can bring about a lot of anxiety. It also doesn’t help to know that hundreds of things can go wrong during your trip. But travelling doesn’t have to be a pain because there are ways to avoid travel stress. From booking all inclusive holidays Thailand Phuket, to preparing yourself mentally, here are some tried-and-tested travel tips on how to handle travel stress.  How To Handle Travel Stress? It Starts With Traveling The Way You Want To… See, there has been a paradigm shift in the way we travel these days, and this I am speaking from my personal experience. There are so many Instagram stories, reels, or moodboards playing in our heads that we create a vague image of what is ideal.  But in reality, if you are not on a business trip, you don’t really need to fit in. You don’t need to have a bucket list of visiting XYZ places because everyone else is doing the same. Your plan of a vacation can be about sitting in a quaint cafe in Europe and having the best pastries and sandwiches there.  It’s absolutely okay! You really need to let it loose and indulge in the spirit of slow tourism where every moment spent is meaningful and cherishable for you.  That’s the best mantra I can give you on how to handle travel stress.  1. Always Plan Ahead “Failing to plan is planning to fail,” so the famous adage says—and it couldn’t be truer when travelling. From choosing the right destination to booking the right flights, having a good plan will not only make travelling a lot easier for you, but it will also keep you from mishaps that are costly and very stressful.  Always be realistic with your timelines when planning. For instance, when booking flights, make sure that you give yourself enough time to get to the airport, given your location.  If you’re departing from a busy airport, it’s best to book an earlier flight, so you can avoid the rush. If you have a layover, make sure that you have at least three hours free until your next flight to make room for possible delays that could make you miss your connecting flight. 2. Don’t DIY Your Trip If You’re Not That Type Of Person Here’s the thing: DIY isn’t for everyone, and that speaks true when travelling. Suppose you’re someone who has a hard time putting a grocery list together. Planning an itinerary can be extra stressful for you.  Thankfully, you don’t have to because there are all-inclusive options for many hotels and resorts around the world.  These packages already include everything from airport transfers to meals and activities. Yes, these are a little pricey; however, they reduce your stress.  3. Make Sure That You’re Mentally Prepared For The Trip Travel is beneficial for your mental health. However, it can also be the salve to your panic and anxiety when you are not prepared for it.  Many of us assume that travel preparation includes simply arranging airfare and packing bags. However, we must realize that travel equals experiencing a new destination, which takes us out of our comfort zone and routine.  So, before we completely lose ourselves in the disarray of travel preparation, it is really important to give ourselves time to prepare mentally for the trip. In addition to proper planning, be sure to squeeze in some familiar routines or activities in your travel schedule. For example, I am a coffee and bread person. So, I will not miss visiting the local coffee shop. However, I always look for a coffee shop near my hotel. Equally important, be sure to avoid last-minute preparation. For example, don’t pack your luggage the night before your early morning flight. It is a guaranteed way to make you tired and stressed before you even get on the airplane.  I make sure that everything is ready at least a day or two in advance. I need to relax and get some well-deserved rest before the trip! 4. Plan Activities To Keep You Entertained During The Boring Moments I still hate waiting at the airports. However, I don’t get as anxious as before about long flight delays. However, I have seen people getting fidgety and stressed on long flights.  I mastered the art of avoiding long-flight anxieties as I started planning travel activities for my daughter. I told myself, “If this little human can have activities planned for the flight, why not me?” So, now I carry my book and download the latest movie or series I want to watch. Of course, pack some snacks to keep my mind busy.  5. Keep Important Documents Protected Make sure to keep valuables in a secure bag. Additionally, it doesn’t hurt to take a scan of your documents. So have backup on your phone in case you lose your printed documents. So, always keep the emergency contact number of the country you are visiting handy. Travel safe!

What To See In Lassen Volcanic National Park: Into The Darkness Of Subway Cave After A Fire Breakout

BY  Sibashree Oct 15, 2024

Lassen Volcanic National Park was in the news recently as the fourth-largest wildfire in California exploded out of proportion. The park's officials evacuated staff from the Mineral community near the park headquarters.  120 people were there in the community, and the evacuation started as the fire started moving east to the park on the evening of 26th July 2024.  However, the park fire reached near containment in August, and on 17th August 2024, the park was partially reopened. You may wonder what to see in Lassen Volcanic National Park after the fire breakout and if there is any significant destruction in the places of interest in the park.  Let me assure you. The park officials stated that the fire had never entered the park. However, there are still risks in the southern part of the park and Mill Creek and Mineral communities.  Nevertheless, the reopened parts of the park are out of danger despite some lingering smoke. So, Subway Cave, located around 15 miles north of Lassen Volcanic National Park, is one of the safest sites to explore after the fire incident. Make a rush, as it remains open from late April to November.  What To See In Lassen Volcanic National Park After The Fire Breakout (Exploring The Underground World Of A Lava Tube) Yes, you got me right! I am talking about the Subway Cave. The self-guided trail inside the cave is ⅓ miles long and 30 feet wide, and complete darkness is inside. So, many call it the journey into darkness. The USDA Forest Service maintains the cave, which remains open from dawn to dusk.  Before I get into more stories and facts about the cave, I want to present the basics you need to know briefly.  Important Facts About Subway Cave, Lassen National Volcanic Park Location in the ParkA 2-minute walk from the parking lot near the junction of “Highway 89” and “Highway 44” in Old StationAmenitiesPicnic TablesDrinking WaterParkingToiletsInterpretive SiteFeesFree (You can make donations)Pet-FriendlyNoParking FacilitiesMany Parking Facilities, Buses and RVsOutdoor ActivitiesInterpretative Sessions, Caving, PicnicTemperature Inside the Cave46 Degree Farrenheit Nearby AttractionShasta County (Mountainous landscape and multiple picnic locations)Nearby Trails*Cinder Crone TrailSpattercone Nature TrailButte Lake to Widow Lake, etc.  *Many hiking trails in the park, such as the Lassen Peak, Bumpass Hell, and Mill Creek Falls, are closed as the park has partially reopened after the recent wildfire explosion. So, check with the park authorities before you plan a hike on the park trails.  This Is How The Subway Cave Was Formed  If you are a keen learner of geology and want to know what to see in Lassen Volcanic National Park, you cannot avoid the lure of Subway Cave. I have already shared an account on the geothermal wonders of the park. This cave is an example of how lava flowed around 20000 years ago and created some magic.  A major lava explosion happened all across the Hat Creek area around 20000 years ago. The top layer of the lava flow became cold and hard in contact with air. Thus, a hard cap was formed. However, there was a continuous flow of molten lava below this cap.  The molten lava drained out Over time, but a hollow tube structure remained there. As you hike this trail, you will find traces of the more recent lava flows.  Route To The Subway Cave Is Bumpass Hell on your list of what to see in Lassen Volcanic National Park? Are you planning a trip to the park soon? Then, you will be disappointed as the Bumpass Hell trek route is closed after the park has reopened following the recent fire breakout.  Further, as Bumpass Hell is closed, you must take the Warner Valley Area route to  Devils Kitchen, which is the cave's opening. Devils Kitchen is a 4.4-mile hike from the Warner Valley Area (camping here is closed for 2024).   Accessing The Subway Cave  You have to climb down metal stairs as you access the Subway Cave. You will get down into a wide opening in the ground. The ground surface has a leveled floor. However, you must be careful as you get off the stair flight.  Further, you must wear sturdy footwear to avoid injuries and difficulties where the floor gets rough.  Fortunately, the ceiling and walls are quite smooth, minimizing the hiking difficulty level while hiking. Also, there is complete darkness inside the cave. So, you will need a flashlight to make it to the end.  The weather inside is a little cold, even in summer. So you will need a light jacket. Moreover, don’t forget to read and follow the interpretative signs through the trail to better understand the place.  The best thing about this park is that it’s 30 feet wide. So, even with complete darkness inside, you never feel suffocated.  What To See In Lassen Volcanic National Park Subway Cave It is not a long walk inside the Subway Cave. However, this short walk is enough to make it feature on the list of what to see in Lassen Volcanic Park.  Lucifer’s Cul-de-sac (An Attraction Very Few Knows About) Have you listened to Satan’s Cul-de-sac from Gangland Buries Its Own? The first thing that may amaze you inside the cave is Lucifer’s Cul-de-sac. There is a split as you enter the cave, and you are to turn to the right if you want to continue the trail. However, you will notice a big room if you are adventurous enough to turn left, when I tell you about Lucifer’s Cul-de-sac, The ceiling height starts from 6 feet and gets higher up to 15 feet. The most amazing thing about this room inside the cave is the rock formation on the ceiling and walls. It’s gothic and justified its name.  https://open.spotify.com/track/6cq37W4OXjEdQRLh2IVQOF As The Hike Advances  The ceiling height will vary as you continue the trek, and there are small boulder-like rock formations in many places. So, be careful with your steps and do not stumble upon them. Also, because of these rock formations, you must not wear an open-toe shoe while walking through the cave.  Nevertheless, the ceiling formation is fascinating, and in one section, it looks like stoned rainfall or water ripples. The section is called the Lavacicle Lane. Molten lava dripped off through the cracks in the ceiling cave, and there were formations of “drip pendants” or “lavacicles.”  Further, as you plan to take the exit, you notice all the colors in the lava rock formation, including green, blue, white, and brown lines.  Getting Out Of The Subway Cave As you approach the end of the cave, you will find a metal stair flight similar to the one at the entrance. From the top of the exit staircase, you can hike through an on-ground trail to the west or north to find the parking lot.  However, I prefer to take another walk through the cave and get back to the entrance. It will be so much fun to explore this unique geological formation again.  Things To Remember Before Getting Into The Darkness Of The Subway Cave  Subway Cave is a hidden gem if you consider what to see in Lassen Volcanic National Park. However, once you take the hike and read the interpretative signs, you will learn why it is geologically unique.  Nevertheless, you must be careful about certain things to ensure complete safety throughout the hike.  You will find rattlesnakes in the trail, and you have to be respectful to these reptiles. You must not make any move to catch or hurt them. Moreover, you cannot go off trails or litter inside the cave.  No food, water, or firelighting is allowed inside the cave. There are picnic areas nearby for you to catch refreshments. Wish you a safe, easy, and fun-filled experience inside the Subway Cave!  Also read Why Include Whale Watching In Your LA Itinerary.
