An Ice Hotel is a temporary hotel made up of snow, sculpted blocks of ice, and some steel framing. They are promoted by their sponsors and have special features for travelers who are interested in novelties and unusual environments, and thus are in the class of destination hotels. Their lobbies are often filled with ice sculptures, and food and beverages are specially chosen for the circumstances.
All of the ice hotels are reconstructed every year, and are dependent upon constant sub-freezing temperatures during construction and operation. The walls, fixtures, and fittings are made entirely of ice, and are held together using a substance known as snice, which takes the place of mortar in a traditional brick-built hotel.
A hotel built of ice and snow, would be the most common response. The first and the largest in the world, someone might add. But we have more thrilling stories to tell.
