A hotel made of ice. A robotic concierge. Interacting with people remotely via a hologram. Electric doorbells that detect body heat and intelligent minibars that inform the hotel when it needs to be restocked.
These are just some of the technologically-advanced amenities you'll find in a few hotels around the world. The travel site, Trivago.com, looked inside eight futuristic hotels. Take a look.
Icehotel, Jukkasjarvi, Sweden
Sculpted out of ice and snow from the nearby Torne River, Icehotel is both a hotel and an art exhibition. Each year, renowned artists are invited 120 miles north of the Arctic Circle to chisel away at 1,000 tons of ice and design the hotel's suites. Though temperatures in the region border on the extreme, the room temperature never drops below minus 5 degrees Celsius, and Icehotel provides thermal clothing and sleeping bags to ensure that guests remain insulated.
Each morning, the staff of the Icehotel in Sweden greet guests with a hot lingonberry juice in bed. After a night braving polar conditions, guests switch to a warmer chalet-style accommodation next door with all the modern comforts. There are a host of activities for visitors to experience, including an overnight dog sled expedition and the Aurora Sky Station in Abisko, where visitors can check out the Northern Lights.
The Marker Hotel, Dublin, Ireland
The Marker Hotel is situated in the heart of Dublin's vibrant Silicon Docks district. Its innovative, six-story checkerboard facade is inspired by Ireland's rugged landscape of bare rocks. By night, the neon lights of Grand Canal Square that shine on The Marker's exterior add to the futuristic feel of the establishment. Guests can unwind in the hotel's full-service spa and wellness center, which features an infinity pool, Jacuzzi and sauna.
The generously-sized rooms at The Marker Hotel in Dublin are designed with geometric interiors and punches of vibrant color. There are three dining options, including the modern Marker Bar, which features a long workbench with directional lighting and docking points for people who wish to remain connected in less formal surroundings.
Hotel 1000, Seattle, Washington
Hotel 1000 in Seattle combines the modern luxuries of a city hotel with the personable service of a boutique property. The hotel's virtual Golf Club allows players to swing balls on 50 of the world's best courses without ever leaving the comfort of the hotel. The Spaahh is a full-service spot for pampering, and the on-site bar and restaurant serves American food and a range of cocktails.
High-tech yet inviting, Hotel 1000 in Seattle makes you feel like you're living a decade in the future. Electronic doorbells scan each room with infrared sensors to detect body heat, informing staff whether rooms are occupied so that guests are not disturbed. Guests also have access to an electronic do-not-disturb button and an intelligent minibar that informs the hotel when it needs to be restocked.
NH Collection Madrid Eurobuilding, Spain
A self-styled "Living Lab," the NH Collection Madrid Eurobuilding feels light-years ahead of other contemporary hotels. The four-star, 431-room hotel offers modern Iberian decor and pioneers technological advances, boasting a huge, ever-changing curved LED screen over the lobby.
Guests of the NH Collection Madrid Eurobuilding in Spain can charge their mobile devices wirelessly and speak to reception face-to-face from the comfort of their room via video-supported tablets. What really leaves you feeling like you've fallen out of a time machine, however, is the 3D telepresence system that allows guests to interact with people remotely via hologram.
Burj Al Arab Jumeirah, Dubai, UAE
Burj Al Arab Jumeirah in Dubai is a symbol of modern Middle Eastern luxury. Guests are greeted at the airport by an air-conditioned, chauffeur-driven Rolls Royce and driven through the orderly and pristine streets of Dubai to the hotel. Each suite in the hotel overlooks the Arabian Gulf and includes a 21-inch iMac, a 24-carat gold iPad and widescreen smart HD TV, as well as 24-hour butler service.
Diners at the Burj Al Arab Jumeirah in Dubai have a choice of nine signature restaurants, with the pick of the bunch the Al Mahara, which serves seafood in an aquarium. The main circular dining area and private dining rooms are lit by the glow of enormous seawater aquaria. The Talise Spa allows guests to relax and rejuvenate in surroundings inspired by the ancient Middle Eastern civilizations.
Yotel New York, NYC
Based three blocks from Times Square, Yotel New York revolutionized hotel check-ins with its one-armed luggage robot called Yobot, the world's first robotic concierge. Guests can rest assured that touchscreen-operated Yobot, sitting behind a glass wall, is safer than the T-1000 series in the "Terminator" films. It deftly grabs, lifts and stores baskets containing luggage and issues a receipt for guests to submit when they want to pick up their bags.
Yotel New York prides itself on delivering "affordable luxury," and this is evident in its small, efficiently-designed rooms. Each room has a 32-inch TV and premium cabins have electronically-controlled beds that gently slide between couch position and the flat bed position with the touch of a button. Each floor has a kitchenette with a microwave oven, allowing guests to grab a late-night bite to eat.
AC Hotel Bella Sky Copenhagen, Denmark
The unique 814-room Bella Sky hotel in Copenhagen is situated right next door to the Bella Center, the 20,000-capacity exhibition and conference center. With tilting twin towers that lean away from each other at an impressive 15 degrees, the hotel is an architectural landmark and one of the largest, most aesthetic hotels in Scandinavia.
Rooms at the Bella Sky hotel in Copenhagen are spacious and furnished with original design furniture and floor-to-ceiling windows as well as free Wi-Fi. Guests can indulge in Nordic cuisine in any of the three restaurants and take in amazing panoramic vistas of the Copenhagen skyline in the Sky Bar.
CitizenM Amsterdam, Netherlands
Who says hotels of the future have to cost a fortune? CitizenM in Amsterdam is ideal for casual travelers and backpackers alike. In shunning conventional hotel staples like trouser presses, bellboys and towel swans, it feels like a home away from home. Each bedroom features an extra-large king-sized bed with blackout blinds and guests can control the entire room using its innovative MoodPad tablet, including adjusting the temperature, TV channels, window blinds, colored lighting and wakeup alarm themes.
There is a library of free movies to explore, as well as free Wi-Fi at the CitizenM hotel in Amsterdam. The lobby is laid out like a living room, decked in Vitra furniture and iMacs, and there are a range of dining options in CanteenM, the hotel bar, including barista-brewed coffee for early risers and signature sandwiches, sushi and warm dishes.
