I know some people will say go to Tokyo, but that is easier said than done.
Disney broke revolutionary ground with rides such as the Matterhorn, The Haunted Mansion, and Pirates of the Carribean. These are Disney quality attractions. They took you out of this world and into another. The only rides built for the first time since 1990 in the American parks that did this as good as the classics were Indiana Jones Adventure at DLR and Tower of Terror. They are fully immersive experiences, like Walt wanted. I have yet to ride Everest, but I will in August, and it will be next year till I get to ride Finding Nemo Submarine Voyage, so I can't judge those two yet. Why can't Disney built more rides that are elaborately detailed, completely immersive, and follow Walt's idea of taking people on incredible adventures?
