Ice Hotel, Jukkasjarvi, Sweden
What first opened in 1990 as an exhibit by a French ice artist has since become a magical and rather chilly chance for guests from around the world to experience the feeling of sleeping in an igloo. Crafted from ice and snow, each year Ice Hotel is rebuilt by visiting artists and creators. Though the temperature never drops below 23 degrees Fahrenheit, guests wears thermal underwear and hats and slip into a sleeping bag atop blocks of ice, a thick mattress, and reindeer skins. Open December 10 to mid-April yearly. (i think. for more info: icehotels.com)
With that said, Japan opened an ice hotel in Alpha Resort Tomamu's ice village, on Hokkaido Island. The living-rooms, bath-rooms and bed-rooms are all made out of ice, and it costs 80,000 yen ($696) to spend the night, for two people.
Dinner is served on an ice plate while drinks come in ice glasses, so you have to sip them quickly, before they freeze.
