For me, so far, I am loving what I am seeing. Especially with the castle. Instead of just being a "weenie" and landmark it looks like Shanghai is really going to make the castle be alive and have things to do in there. That's fantastic.
I always thought it was a shame that you really can't go inside the Disney castles all that much. Sure, in California you have the little sleeping beauty walkthrough and in Florida they have the Cinderella's Table and the little shops and the Cinderella's Suite for VIPs...but there aren't attractions in there.
The castle is such a great place for a meet and greet, for a dark ride, and the dock for a boat ride. I think that Shanghai is going to have most of that from what I understand. I think it also has the restaurant too.
I love how every new Disney park improves on the past. I hope one day that there will be a Disney park in Australia or a new park built here in the US in Texas. I'd love to visit those. But, I bet the only new Disney parks will either be in Asia or in Brazil. I doubt the US will ever get a new park and if they build anything in Australia it will just be a resort like Aulani.
