Marriott International, the big Bethesda-based hotel manager, landed the contract to manage the 692-room Doral Golf Resort & Spa in Miami.

That may bode well for Marriott's resort hotel business -- it manages 60 resorts worldwide -- because Doral's owner, CNL Hospitality Properties of Orlando, bought the Doral and five other upscale resorts in April and, while it is keeping on KSL Recreation, the old owner, to manage the other resorts now, it isn't ruling out new managers for those as well.

The purchase of Doral, the 780-room Grand Wailea Resort & Spa on Maui, the 796-room La Quinta Resort & Club in California, and three other resorts for $1.4 billion in cash and assumption of almost $800 million in debt bulked up CNL into the nation's second-largest hotel real estate investment trust.

CNL plans to invest more than $40 million in Doral over the next three years, including building additional meeting space. On 650 acres, the resort sports five championship golf courses, 90,000 square feet of meeting space, five restaurants, the Jim McLean Golf School and the Arthur Ashe Tennis Center.

MeriStar Hospitality in Arlington, one of the nation's largest hotel real estate investment trusts, said its six hotels on Florida's Captiva and Sanibel islands were hit by Hurricane Charley but early assessments suggest repairs won't have a major impact on the REIT's bottom line. "While it is too early to fully estimate the extent of the damage, our initial assessment suggests that there was not a significant amount of structural damage to the facilities, but the landscaping damage was extensive on Captiva Island," said Paul W. Whetsell, MeriStar's chairman and chief executive.
