Resort hotels and motels offer luxurious surroundings with a variety of recreational facilities such as swimming pools, golf courses, tennis courts, gamerooms, and health spas, as well as planned social activities and entertainment. Resorts are located primarily in vacation destinations near mountains, the seashore, or other attractions. As a result, the business of many resorts fluctuates with the season. Some resort hotels and motels provide additional convention and conference facilities to encourage customers to combine business with pleasure. During their off season, these establishments solicit conventions, sales meetings, and incentive tours to fill their otherwise empty rooms.
