Over the past 20 years and particularly the past five there's been a big growth in the number of places people can sleep in igloos or ice hotels.
Many thousands of skiers and boarders have tried it and mostly had fuiun but some did not enjoy the cold and some have never tried it because they think it will be too cold.
Iglu Dorf (www.iglu-dorf.ch), one of the main 'chains' of igloo villages at half a dozen top resorts in the Alps and Andorra, which already installed hot tubs in their 'romantic' igloos hopes to attract that market with the launch of their comfortable heated 'Hot Igloo' in Engelberg.
From this you can marvel at the clear winter sky through the room's transparent dome roof and enjoy all the luxuries of a hotel room, right next to the original Igloo Village above Engelberg, so that guests can take their meals there too.
