Ooooh...wishlists for both parks:
I would really, really love an on property Anaheim hostel. Or even a true value on property hotel. I would pay up to 80 bucks for a bed in a dorm room. Anaheim is so freaking expensive in summer. Or I would love an Anaheim fort wilderness. Will never happen. But I'd rather pay 100 dollars for awesome Disney camping than 100 dollars for motel 6 main gate. (There is a a hostel in Fullerton, 7 miles away, but it's creepy and not really on a transit line. I don't want to rent a car- that's the whole point of hostelling!)
Or how about a "bunk house" hostel at the actual fort wilderness. Ban families. Establish quiet hours and a maximum stay like the major city hostels. There are enough solo young adult disney fans (or even retirees) that they could make a killing off that, plus it would free up hotel rooms for the families.
Other than that, just would like to see more of the actual recent Disney movies. How does Pandora get a land but Tangled only gets a bathroom? Why do we have a guardian ride but no Mulan ride? Why is Frozen in Epcot at all? I like the ride, but I think it was a cheap and sleazy way to do that. They should either revamp Epcot entirely or refurbish it so it actually works as it was originally intended to.
And what the heck is with the 3D/video stuff instead of the elaborate rides? On thrill or futuristic stuff, sure. But not on ratatouille, or nemo. I want old fanshioned props! There is a reason jungle cruise, Indy, pirates, haunted mansion are all iconic.
