We dined there the night it opened and there was a great amount of confusion which is understandable in a newly opened restaurant. We have DDE and they refused to honor it after we had been told repeatedly by Disney that they accepted it. It was quite pricey and without the 20% discount of DDE, it isn't really worth it. The manager gave us his discount of 20% because the confusion was not our fault - many others there had the same problem. This was back in October and I don't think it has changed. Originally RR said they would accept it, but then backed out because they really didn't know what the DDE was. (that's what we were told by the manager). They are not Disney owned, so obviously the two corporations needed to work some things out. I would not rely on calling Disney, I would call RR directly to see if anything has changed.
Oh, and when we went the show wasn't being performed until MUCH later that night, so we weren't able to see any talent. Sorry I can't help you with that.
