Hotels in China are classified into first class, second class and third class based on their star rating. Five stars and most four star hotels are in the first class. Guestrooms in first class all have fully-fitted bathrooms, refrigerators, telephones and satellite TV. They have fully-adjustable climate control through central air-conditioning facilities. Other ancillary facilities provided by these hotels includes such things as business centers, conference facilities, beauty parlors, saunas, foreign exchange, bowling centers disco ball rooms, swimming pools, gymnasiums, restaurants, coffees, shopping centers and bars which are open 24 hours a day. The second class generally includes three star hotels and some two star ones. Guestrooms facilities and services are not up to the standard as those in first class hotels. Tour groups normally prefer to stay in second class hotels. Third class hotels are much like motels in western countries in terms of facilities and services. Hardware facilities in such hotels are of course inferior to those provided by second class hotels. But they offer prices 50% or more below those second class hotels. As a result, they are popular with many tourists
