Pretty small and manageable  you can easily hit all the highlights within the first three or four hours of the park opening (assuming you go at line drop and don't stop for breakfast character meets etc). The park has a lot of repackaged rides areas from Disneyworld and Anaheim Disneyland, which was fine but nothing new. The best rides that are relatively novel to Hong Kong are Iron Man and Mystic Manor (the best, obviously). My favorite part of the whole park was actually the shows, which were really well done and blended Cantonese and English in a very accessible and interesting way. Definitely try to catch the Jedi Training  it was hilarious and great. The shows were the most identifiably  Hong Kong  part of the park, so they were really memorable for me, as a westerner. If you need an afternoon beer, River View Cafe has one beer on tap.
