We've never been entirely sure what the appeal of an ice hotel is - what's so great about a frozen pillow? - but they keep cropping up. Now Iglu-Dorf has moved one step down the thermostat with its chain of igloo hotels in Switzerland, Germany, and Andorra. You, too, can stay in a "romantic igloo suite" - complete with expedition-grade sleeping bags and private jacuzzi. No word on whether the suite comes with a butler to chip the ice out when your tub freezes over.
