A winter wonderland on the outskirts of Quebec City has become one of Canada's hottest attractions and most sought out accommodations. Guests stay close for warmth in sleeping bags on beds of ice, hats pulled over their ears to prevent frostbite, while sipping cocktails   in glasses also made of ice. A cool place to host a memorable wedding or for a romantic getaway, the Quebec Ice Hotel has attracted 600,000 curious tourists, including 30,000 who stayed overnight, since opening seasonally 11 years ago. Like Victoria and Jeremy Martin, dozens of couples will exchange vows   this winter in a temporary church next to the hotel, made entirely from blocks of ice with seats covered in furs. Average temperatures fall below minus 20 degrees C (minus four F) in winter, but inside the hotel's 36 rooms it is relatively comfortable. Thick walls of packed snow and ice act as an _ , trapping body heat inside. Each room is uniquely decorated, using designs created by Quebec architecture students. Two hotel bars also sell special cocktails in ice glasses. First-time guests of the hotel, however, are recommended to stay only one night as sleeping in sub-zero temperatures is not very refreshing. This year for the first time the ice hotel has teamed up with a brick and concrete Quebec City hotel to offer packages  for one-night accommodations at each. Prices for one night only at the ice hotel start at 200 US dollars per person. The 3,000-square-metre (32,300-square-feet) buildings take six weeks starting in December to build, using 15,000 tons of snow and 500 tons of ice, at a cost of some 750,000 US dollars. Eleven weeks after its seasonal grand opening, the hotel will close on March 27 and then melt away with the arrival of spring. First-time guests are advised to stay there only one night because   _  .
