jungle baggie, you may wish to try Universal Studios, Efteling and maybe Europa Park/Phantasialand. They also can and do rival Disney.
That aside, for attractions missing in DLP, I would love to see Splash Mountain (it runs in Tokyo - with a winter setting, they get snow and ice too) and Indy.
But I would love more educational story telling attractions akin to what you find at Epcot. Disney used to be more than characters and rides, there were things to be learned as well.
I would love an American Adventure type attraction about European History (though the wonderful Le Visionarium used to do a great job at it - much better than stupid buzz).
I would love a Journey to the Centre of the Earth or 20k attraction too.
anything that is not toon related is welcome.
Also a Mad House could be good, but Villa Volta and the one at Phantasialand are really awesome already, not sure if Disney could plus it more.
