When I researched the main Tokyo Disney park, the two rides most people suggested to check out were Pooh's Hunny Hunt and Monsters, Inc. Ride & Go Seek. Personally, I was underwhelmed by the Monsters, Inc. ride, which felt too similar to Disneyland's Monsters, Inc. Mike & Sulley to the Rescue! attraction. I'd recommend anyone visiting the park to go straight to Pooh's Hunny Hunt at arrival, get a FastPass, then ride it, so you get to ride it at least twice. The trackless, immersive, dark ride is unlike anything you'll ride at Disneyland or Disney World.
