Hilton Hotels Corp. will manage a new golf resort and spa in Thailand, marking the debut of the company's Doubletree brand in Asia and the Pacific. The 358-room Doubletree Golf Resort & Spa will overlook the fairway of the Sriracha Golf Club, designed by Gary Player and host of the 1993 Thailand Open. Hilton already operates four hotels in Thailand; the addition of a Doubletree property to the roster is part of Hilton's new global expansion effort for the brand.
