An ice hotel is a temporary hotel made up entirely of snow and sculpted blocks of ice. 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 hotel. Their lobbies are often filled with ice sculpture, 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-zero temperatures during construction and operation. The walls, fixtures, and fittings are made entirely of ice, and are held together using a substance known as since, which takes the place of mortar in a traditional brick-built hotel
