Royal Resort and Casino (RRC), a publicly traded company, caters to affluent customers seeking plush surroundings, high-quality food and entertainment, and all the "glitz" associated with the best resorts and casinos. RRC consists of three divisions: hotel, gaming, and entertainment. The hotel division manages the reservation system and lodging operations. Gaming consists of operations, security, and junkets. Junkets offers complimentary air fare and lodging and entertainment at RRC for customers known to wager large sums. The entertainment division consists of restaurants, lounges, catering, and shows. It books lounge shows and top-name entertainment in the theater. Although many of those people attending the shows and eating in the restaurants stay at RRC, customers staying at other hotels and casinos in the area also frequent RRC's shows, restaurants, and gaming operations.
