Perhaps because of his start in the trade show business, Adelson focused his hotel efforts on courting the convention and trade show industry. At the time, when other hotels were focusing on gambling, his approach was considered unorthodox: the traditional strategy was to keep hotel rooms minimal, so as to encourage guests to spend as much time as possible in the casino. Adelson, however, had all his hotel rooms made into luxury suites; he put in mini-bars and big screen televisions; and he created comfortable work spaces in every room. By doing all this, he counted on business from the Sands Expo and Convention Center to keep mid-week occupancy strong. This proved correct; the company now makes more money in Las Vegas from conventions than gambling. And Adelson's convention-centered approach is no longer considered unorthodox, but rather the paradigm in the hospitality industry in Las Vegas.
