Apparently Texas Thrillseekers is spreading a rumor that HFEC has put in a bid for SFOT and a couple other SF properties (presumably the adjacent water park in Dallas and maybe FC or DL?)
SFOT supposedly has an odd ownership setup that dates back to the original setup of the park. It's kind of like Dollywood, but somewhat dysfunctional with disputes about how the park should be developed. Supposedly that is one reason why investments have been fairly small despite the massive growth potential of the park. This is one reason why SF may be pressured or coerced into selling the park.
I don't know that the rumor has any weight, but I do know that HFEC has tried to purchase SF properties before. When SF sold off Elitch, Darien, FC and several other properties during their 2006 bankruptcy, HFEC put in a bid but was beat out by CNL. For some reason I believe SFMM was part of the deal at the time, but HFEC didn't want it, and that soured the deal.
