Ha ha, yes, great to see but I can't imagine I'd be overly keen on sleeping there though I would for the experience of it and I believe you don't feel cold from looking at the snow...
When you compare the Ice Hotel to a huge fridge, it doesn't seem all that appealing 😂 And having the place open all year long may be a bit like having Christmas in the summer though I guess some people do, so why not have the Ice Hotel available a all year long.. :)
