I went to the Disney world in Tokyo and LA., which you can stay few days for these two, but for the Hong Kong one, sorry to tell you that you can finish it in 3 to 4 hours. It is extremely small and the worst is the Cinderella castle, they scare it down to a smaller scale which make it looks really ridiculous. If you had never been to a Disney world, well you can give it a go, but if you tried other Disney world, don't bother and go to ocean park please
