Gandalf, thanks for the video, I really did not know that in Quebec is an Ice Hotel.
My aunt said to me that it was not cold at all because I imagine all the ice makes a good temperature inside (even if you keep your boots and your coat.) They took a drink also, in ice glasses. I imagine living in an igloo is the same, in fact surely these hotels are made like igloos, but bigger.
So maybe we should learn how to do an igloo... for the next Ice Age. ;)
