Also just a side note, while I don't doubt that laceyb was given the information (we all know how Disney can be with info) I highly doubt that if they were to cancel the show they would not refund the tickets...it is Disney after all, if they did not provide the service with which you paid for they are going to give it back it is in their nature (and best interest)... That of course is just my opinion, I have never had expereince with that...
