For most other Disney parks, this page would be pretty long. However that's not the case for Hong Kong. Having said that, not every attraction has been listed here.
AUTOPIA: The electric vehicles are a lot more modern than at other parks. That doesn't mean it's actually any good though.
DUMBO THE FLYING ELEPHANT: Come on! It had to be included.
THE MANY ADVENTURES OF WINNIE THE POOH: A fun family attraction featuring some excellent effects.
MICKEY'S PHILHARMAGIC: An excellent 3D show, featuring a host of popular Disney characters and songs.
STITCH ENCOUNTER: A highly impressive interactive show. Aimed more at kids, but still very entertaining.
