I went to DisneySea on Day 3.
I choose to go to DisneySea because I have been to LA's DisneyLand and DisneySea only available in Tokyo.
DisneySea just situated beside Tokyo Disneyland. We took JR line reaching at Maihama Station. Paid 250yen hooped on to Disney Resort Line to reach at DisneySea Station.
1 day DisneySea passport is 5800yen.
Through out the day there were a lot of shows and parades in DisneySea.
The biggest Parade of the day that you shouldnt miss is "The Legend of Mysthica" which it displayed at the center of Mediterranean Harbour. You can see the Disney characters and creatures like dragon and unicorn.
Over at waterfront Park you can have Big Band Beat musical theather. The only English Speaking musical show..
There are some roller coaster rides likes Indiana Jones Adventure at Lost River Delta, Journey to the Center of the Earth at Mysterious Island and etc...
Other Attractions that I enjoyed are Sindbads's storybook Voyage (in japanese which i dont understand), 20K Leagues under the sea...
