Marriott International has completed its acquisition of the Gaylord brand and hotel management company. Gaylord's shareholders approved the $210 million sale last week, as well as Gaylord Entertainment's transition to a real-estate investment trust. As of today, Gaylord Entertainment has merged with Ryman Hospitality Partners Inc. and assumed the latter's name. Under long-term agreements, Ryman will continue to own the existing four Gaylord hotels that will be managed by Marriott. Also effective today, Marriott will manage three Nashville attractions: the General Jackson Showboat, Gaylord Springs Golf Links and the Wildhorse Saloon. Beginning Dec. 1, Marriott will manage the 308-room Radisson Hotel Opryland, which will then be renamed The Inn at Opryland, a Gaylord Hotel. Ryman will maintain ownership of all of those properties. In total, Marriott will add five hotels, or 8,100 rooms, to its inventory. Beginning in late October, Marriott Rewards points can be earned and redeemed at the Gaylord Texan on Lake Grapevine near Dallas; the Gaylord Palms in Kissimmee, Fla.; and the Gaylord National on the Potomac in National Harbor, Md. As of Dec. 1, points may be earned and redeemed at the Inn at Opryland, a Gaylord Hotel; and beginning in Feb. 2013, the Gaylord Opryland Hotel in Nashville will honor the loyalty program points.
