Bob Gault, who led Universal Orlando through tough tourism times following the Sept. 11, 2001, attacks, then a couple of boom years, then another slide, is retiring as the theme park resort's president Dec. 5. Bill Davis, a former SeaWorld of Florida general manager, will replace him, becoming the next chief operating officer of Universal's resort with two of the world's largest theme parks, Universal Studios and Islands of Adventure, the CityWalk entertainment district and three resort hotels.
