Numerous luxury hotels, casinos and nightclubs were constructed during the 1930s to serve Havana's burgeoning tourist industry, which greatly benefited by the U.S. prohibition on alcohol from 1920 to 1933. In the 1930s, organized crime characters were aware of Havana's nightclub and casino life, and they made their inroads in the city. Santo Trafficante Jr. took the roulette wheel at the Sans Souci Casino, Meyer Lansky directed the Hotel Habana Riviera, with Lucky Luciano at the Hotel Nacional Casino. At the time, Havana became an exotic capital of appeal and numerous activities ranging from marinas, grand prix car racing, musical shows, and parks. It was also the favorite destination of sex tourists.
