Rides that exist at Tokyo DisneySea that would be great additions in the U.S.
Journey to the Center of the Earth
20K Leagues Under the Sea (not the same as the original WDW ride)
Indiana Jones Adventure (exists in CA, but need one in FL)
Magic Lamp Theater - Genii Magic Show (3-D movie enhanced with animatronics and live magicians)
Actually, what I would love to see is the entire DisneySea park recreated in Orlando (replace Tower of Terror and Turtle Talk, since those are already in Orlando, but everything else would make unique additions to the WDW experience).
