The Ice Hotel

Are you going into skiing? Is winter your favorite time of year? If you like snow and ice, maybe you should stay at Ice Hotel in Quebec, Canada. But, you can only check in at this hotel during the winter. Why ? Because this hotel is built every December. It has 32 rooms and 80 people can stay there each night. The hotel even has a movie theatre, art gallery, and church. Of course, all of these parts of the hotel are made of ice. In fact, all the furniture, art, lights, and even plates and drinking glasses are made out of ice.

Because this hotel is so unusual, it is becoming very popular. People from all over the world come to the Ice Hotel to look at the fantastic ice art, drink and eat from designed ice dishes and experience the unique atmosphere (独特的气氛). Some couples have even got married in the hotel's ice church. But all these guests keep their winter coats on! Because of all the ice, the temperature inside the hotel is always between - 2ºC and - 5ºC. Surprisingly, sleeping is not a problem in the freezing cold hotel rooms. Every guest gets a special cold-weather sleeping bag and some fur blankets. These keep the room cozy and warm until morning.
