I agree with 100% what you said about Shanghai. My initial thoughts about the park was excellent and during grand opening day, I put it in my top 3 parks. But that was because about 1/3 of the people in there were Disney fans from Japan and US, lots of CM were from Hong Kong or overseas, they only let about 30,00 people in, almost all the effects were working well etc. Then the second time I went there during winter break, I would say the park is rather chaotic with Mainland Chinese CM not well trained enough to handle a lot of the situations.
Hong Kong has been going really strong lately, I have high hope for that park's future!
