Hotels.com released on August 14 its list of the world’s biggest, oldest, greenest and other such hotels deserving a superlative adjective in their description.

World’s Tallest Hotel:
At 321 meters high, the self-styled “7 star hotel” sits on a man-made island, includes its own Rolls Royce fleet, helicopter landing platform and some of the world’s most expensive rooms, at up to €12,000 per night. The Burj Al Arab won’t hold its title as world’s tallest hotel for too long, as its neighbor the Rose Tower is due for completion at the end of this year, but it will likely still merit some interest.

World’s Largest Hotel (number of rooms): The Palazzo Resort Hotel & Casino – Las Vegas
With 8,108 rooms the hotel is basically a mini-city with a Lamborghini dealership, a Barney’s New York and, of course, a casino.

World’s Oldest Hotel: Hoshi Ryokan – Komatsu, Japan
This hotel dates its opening back to 718 and has been run by the same family for 46 generations. Decidedly outdated with a scant 100 rooms, the welcoming traditional tea ceremony reportedly makes up for any lack of modernity.

World’s Most Expensive Hotel Room: Royal Villa at Grand Resort Lagonissi – Athens
At nearly €40,000 per night, it better have its own butler. Which it does, along with a dedicated chef and pianist, which you can enjoy after going for a spin around the Greek Islands in the resort’s Lear jet.

World’s Most Expensive Hotel to Build: Emirates Palace, Abu Dhabi
At over €3 billion in construction costs, this hotel includes 70 soccer fields and 1,002 Swarovski crystal chandeliers.

World’s Largest Hotel Room: Royal Suite in the Grand Hills Hotel & Spa – Broummana, Lebanon
The suite is six floors, totalling more than 8,000 square meters. And why settle for one swimming pool when you can have two?

World’s Coldest Hotel: Icehotel – Jukkasjarvi, Sweden
With rooms built from ice and snow, Icehotel may offer the only hotel with air conditioning permanently set between -5 and -8 degrees Centigrade. You can drink designer cocktails served from ice glasses, and you probably won’t need extra ice cubes.

World’s Highest Hotel (altitude above sea level): Hotel Everest View – Nepal
Set on the tallest mountain in the world, Mount Everest, this hotel is nearly 4,000 meters above sea level, offering awe-inspiring views of the mountain as well as Sagarmatha National Park. The only access to the hotel is via helicopter.

World’s Most Eco-Friendly Hotel: Daintree Eco Lodge & Spa – Queensland, Australia
Set in the world’s oldest rainforest, 15 villas put guests at one with nature, if nature spontaneously produced five-star hotels. The hotel was named Leading Eco Lodge of the World in 2007 thanks to its green habits like using solar power, low-energy lights, having an organic farm to grow its own produce, having no electrical appliances, as well as composting and recycling.
