DisneySea is broken into 7 lands. You can view those online.
A couple of ride notes:
Journey into the Center of the Earth to me uses the technolgy of Test Track or the old Rocket Rods at DL to send you through a fast exploration of the Earth's inside.
Indiana Jones Adventure: Temple of the Crystal Skull was pretty much like the ride at DL (The forbidden eye). Few things were changed for the area it is located in. The cobra resembled more of a dragon type snake and so forth. Indie speaks Japanese at the end of the ride.
I got a few other rides in at DisneySea, but tried to do both parks in one day due to wanting to get home to my wife and baby. I flew from Taiwan to Tokyo after my last meeting. Took a bus from the airport to the Hilton. Went to Ikspiari for dinner. I started the next morning at 7am and went till 10pm when the parks closed. Then got up the next morning and caught my flight back to Dallas. I want to go back during a non-busy time, if there is a time for a more liesure exploration of both parks with my family. At the TDL, I got a fast pass for Big Thunder Mountain railroad and when I went back to ride it, the fast pass wait was 90 minutes... I rode many other rides though.
I found the maps to be interesting. The English version is a lot thinner than the Japanese version. They have pages showing some of the sovenirs that you can find at the park and some different meal options. I was looking for a t-shirt from each park for my soveniers, but came home with only a t-shirt from Planet Hollywood that is located in Ikspiari that says Tokyo
Disneyland Resort on it. If you want tins of candy and cookies, you will find pretty much all shapes and sizes in the stores. Different than what we see in the shops of WDW and DL. If you want anything to personalize your cell phone, you are in luck there too.
So what kind of information are you looking for?
