Hotel de Glace, Quebec
This hotel just outside of Canada's Quebec City is open only in the wintertime for an obvious reason: It is made entirely of ice. Popular with non-hotel guests because of its wedding chapel and “ice bar,” de Glace has a varying number of rooms each winter because it must be rebuilt annually once the weather gets cold enough. Some of the guest rooms have snow sculptures and fireplaces. Lighting is strategically placed so that the natural transparency and reflective qualities of the ice create a romantic atmosphere. Comforters and furnishings make it possible to actually enjoy a good night’s sleep despite the Arctic-like surroundings. Room packages start at about $400 per night, so the experience is not cheap, but you are unlikely to find anything else quite like the Hotel de Glace in North America.
