We are very close to going to Tokyo Disney. I was thinking about making a stopover on our next trip to Thailand.
The only concern I have heard is that some attractions do not have english translation, and therefore something is lost. I specifically heard this about some of the rides at Disney Seas.
The park itself is easily reachable from Tokyo by train. There is a stop right at the park. As for prices, they didn't seem as outrageous as I was expecting. The one thing that seemed very expensive were hotels.
