We were in WDW in December with two 12 year olds and we were paying cash. The only time that we had a problem ordering off the kids menu was at the Plaza Restaurant in MK. My son wanted the grilled cheese and the CM said that they didn't have one. I said don't you have one on the kid's menu and she said, he will have to pay the adult price for it. I thought that was kinda crummy because no one else all week had made a point of it, but I just said, well, he wants a grilled cheese so yes we want the adult grilled cheese. She rolled her eyes at me and took the order. The thing is, there isn't an "adult" grilled cheese on the menu, just a grilled cheese on the kids menu. We have gotten grilled cheese sandwiches there for years for the kids with no problems. I guess she must have been having a bad day.
