With the exception of the themeless Contemporary
the other Disney-owned properties depend on a historical tourist-catered model.
Disney fandom really should come with an introduction booklet to explain the basics.
One of the first concepts for the hotels at WDW was to build them inside the Magic Kingdom. This quickly became impractical, but the basic concept of matching the resort and park theme stuck. Then when the project picked up the Disney
World name, the theme for the resorts was extended so that resorts would also include an international theme.
The theme for each resort was set by how it would appear from inside the park. The Polynesian Village and Asian Resorts (to have built where the Grand Floridian is now) are the backdrops to Adventureland. The Persian Resort would have been seen from Fantasyland as the towers of the palace from 1001 Arabian Nights. The Venetian resort was considered the old country across the sea from turn-of-the-century Main Street. And the internationalist modern Contemporary is the background for Tomorrowland. When the hotel opened in 1971 it really was amazing the largest A-frame structure in the world at the time and one of the few building with a massive atrium.
Just because everyones copied the design in the last thirty years doesnt mean it wasnt unique in its day. We can blame the current management for not keeping the resort up to standards.
In the Eisner Era, there were attempts to keep the overall theme going. The Grand Floridian is a stylistic match for Main Street. Most of the other resorts attempted to at least maintain the World theme Caribbean Beach, Coronado, Dixie Landings even if that theme quickly devolved to be just Eisners moldy world of the east coast snobbish elite (Boardwalk, Yacht & Beach, Sarasota, Key West).
The Swan and Dolphin broke all the themes because it was more important for Eisner to cuddle up to Big Name Architects than it was to build something that would fit at WDW. And the All Stars and Pop dont have any theme because Disney is now too cheap and too lazy to bother with such matters. If putting a sombrero in a New Jeresy Taco Bell can be considered themeing, Disney figured a three story can of Play-Dough would work as well.
Somewhere, Walt sheds another tear.
And way back around the time when the Disney/MGM Studios was being built, there was a concept to build several resorts based around either specific movies (
Gone with the Wind,
The Wizard of Oz) or around movie genres (westerns, musicals, horror)
