Theme-park operator Six Flags Inc. sold seven of its 30 North American parks for $312 million. Jacksonville, Fla., park operator PARC 7F-Operations Corp bought the parks, but plans to sell them to Orlando-based real-estate trust CNL Income Properties. That company will then lease the parks back to PARC, which is expected to operate them. The seven parks are Six Flags Darien Lake near Buffalo; Six Flags Elitch Gardens in Denver; Frontier City and the White Water Bay water park in Oklahoma City; SplashTown in Houston; Waterworld USA in Concord, Calif.; and Wild Waves and Enchanted Village in Seattle. The sales are expected to close in March and help Six Flags, which has struggled with falling attendance and a large debt load. While Darien Lake and Elitch Gardens will no longer carry the Six Flags brand under the new ownership, The Associated Press reports any 2007 season passes will continue to be honored at all Six Flags branded parks.
