My wife and I visited Tokyo Disneyland and Tokyo Disney Sea in 2002. We had an absolute ball. After having visited the Magic Kingdom and Disneyland many times, I anticipated that we would spend the vast majority of our time at Tokyo Disney Sea since Tokyo Disneyland was reported to be so similar to the Magic Kingdom. I was very wrong. Both parks are great fun.
Tokyo Disney Sea has wonderful attractions like 20,000 Leagues Under the Sea (very different from the former Magic Kingdom attraction), Seven Voyages of Sinbad, Storm Rider, Journey to the Center of the Earth, and Indiana Jones and the Temple of the Crystal Skull (a fun twist on the Disneyland attraction). I should up load our photos. Just great, immersive environments, and friendly and attentive Cast Members.
Our hotel (Hilton Tokyo Bay) had large rooms with four full size beds and views of either Tokyo Bay or the parks.
We had a great time, and are looking forward to going back.
