The Walt Disney World Swan and Dolphin are owned by
Tishman Hotel Corporation, a part Tishman Realty & Construction Co., Inc., the contractor for much or Epcot.
The story goes like this: Walt Disney Productions (as the company was called before the Eisner-Wells management team was brought in) recognized that WDW needed more hotels. But after the huge capital investment in what was then called EPCOT Center, they made the financial decision not to build the hotels themselves. Tishman got the nod. The new management team brought in new financing, and would have liked to stop the Tishman Hotel deal, but they were contractually bound. The story continues that Tishman planned to build typical, bland, unthemed hotels. Eisner is an architecture buff, so Disney negoitiated an arrangement whereby Tishman would build the hotels, but The Walt Disney Company would pick the architect. Eisner picked Michael Graves, whose distinctive designs are sometimes beautiful, sometimes ugly -- but never boring or bland.
Originally, the Dolphin was affiliated with Sheraton and the Swan with Westin -- back when Sheraton and Westin were seperate companies. Now Sheraton and Westin are both owned by Starwood. The hotels are now marketed as
The Walt Disney World Swan and Dolphin, and are listed in the Sheraton and Westin directories but without being branded as Sheraton and Westin hotels.
I think it's highly unlikely that these hotels would be imploded, even after the current contract between Tishman and Disney runs out. It's even less likely that Disney would buy out the contract just in order to implode the buildings.
