Interesting topic! I am happy to see that no one had the kind of wait I once had.
This happened about 4 years ago. We had a PS at 1900 Park Fare, for the dinner character meal. This trip was with extended family so we needed a very large table! I think we had 7 adults and 10 kids, total.
Well, the wait ended up being over an hour. We had been at the Magic Kingdom since our 8:00 A.M. PS at Cinderella's Royal table, so the kids and even the adults were tired, hungry and gettin' cranky.
I was extremely patient and didn't cop an attitude, but I stood right at the podium the entire time, and received periodic updates on the status of our table.
When we were finally seated, all was well in about 30 seconds and the long wait was forgotten. The characters were wonderful, the food was good and everyone was having a great time! The adults enjoyed several nice bottles of wine and we watched the kids have a ball with Cinderella, Belle, etc.
I was totally delighted and floored when it was time for the check and the manager came over and said they were comping our entire bill for our entire party!! Not something any of us expected, but it definitely told us something about Disney's commitment to the customer!
