I've been to Paris, Florida, Shanghai and Hong Kong. Florida was the best just because of the scale of it and different parts, I also liked Paris as it's kind of a 'best of' and far cheaper to get to from the UK.
I went to Hong Kong in May last year and really enjoyed it, it was small but we went on a stormy day (free tickets so if it got too bad we didn't mind leaving again), and it was dead so we went on all the big rides multiple times. I think our longest queue was 10 minutes!
The parade was really good as well, having been to Shanghai when there was no parade I had low expectations, but it was just as good as Western Disneyland's and again because it was pretty empty we had a great viewing spot.
Shanghai was the worst purely because it doesn't feel very magical, although their Pirates of the Caribbean ride is the best one!
Desperate to go to Tokyo but the expense has stopped me, especially because if I'm going to Tokyo I also want to blow money on sushi and Sanrio stuff! Maybe for my birthday next year!
I was supposed to go back to Hong Kong in January and they closed the park the day before I was due to go

At least I got my flight refunded.
