I also like the idea of a "Star Wars Land." They should put it in Tomorrowland, in which the ideas that were rumored this past year would be a great addition to the park.
Another great idea would be "Marvel Land." They could put the Iron Man a Ride that is currently being built in Hong Kong Disneyland. That would be a nice addition to Disneyland or California Adventure Park. Or thru could create a Captain America ride, since the new movie is very popular.
To be honest, you know what would be cool and classic? If they made a Mickey and Friends ride at Disneyland. They could make it a dark ride, similar to Peter Pan and Snow White. They could have Mickey, Minnie, Goofy, Pluto, Donald, etc... They could create some type of story about Mickey and the characters. That would be such a classic ride.
While Disney does not need a SoCal response, the company does need to keep moving forward. And utilizing Star Wars, Marvel, and Frozen to further enhance the Disneyland Resort is the way to go. Avatar should remain unique to Animal Kingdom just like Cars Land should remain unique to DCA.
As for the Society of Adventurers and Explorers, it needs to go to Epcot.
Open a Heroes and Villains park on that area of land they own southeast of the others with some infrastructure joining the two plots (not buses).
Marvel, Star Wars, Pixar, Tron. So much great IP to chose from. Have a hero side of the park mirrored by the villains on the other side. Could be awesome.
On another note I'd love to see Disney introduce SEA to its US parks, with the idea that each park has a unique attraction related to their own member of SEA, with Tokyo and Hong Kong already having theirs. Rather than importing mystic manor, I think they should develop an Up themed ride because I'm sure that with his Zeppelin that Carl Fredrickson would join the illustrious society (or maybe Charles Muntz was a fallen member).
Tying them in together with other SEA rides would provide further incentive to see the other unique rides around the world and could possibly provide a new franchise opportunity for Disney, cause they obviously need more.........
Now, if the Disney brass saw the opportunity to maximize revenues and make the Disneyland Resort more of a destination resort than it already is by adding a third gate, I would love to see a park that uses some of the attractions and lands from Tokyo DisneySea with additional areas devoted to Marvel and Star Wars. That would be totally awesome.
Disneyland will probably get Frozen bathrooms with a inspiring "Let it Go" soundtrack and ice in the toilets. End winter and your constipation.
