“The Broadway League does not endorse a casino in Times Square,” the group said in a statement. And local support is critical: The state’s licensing process requires a local board to approve any site. Local leaders and the Broadway Theatre League were already quick to pan a Times Square casino. And so too will be the opposition - particularly for a casino in heavily congested Manhattan. New York City is the largest untapped gambling market in the nation, and the competition for the licenses will be fierce. “We believe that Times Square offers the best location for a new resort casino that can attract tourists and benefit local businesses,” Marc Holliday, CEO of SL Green, said in a statement.
