This is a perfect way for Disney to get extra gravy money for people who make reservations and dont use it. I just came back from WDW on Monday night. There is no walk ups allowed, but they dont express that when you looking for info on restaurants. (ITS A VERY RARE THING )
I also went too the French restaurant on Saturday night and a couple SKIPPED OUT ON PAYING THE BILL. We saw a waiter run out of the rest and look for them. As soon as we saw this we knew something was wrong. We asked our waiter what happend and he told us. He said these things do happen.The waiter never say them again, and he was out a tip and money for the restaurant. All the years I have gone to disney I could not believe it happend.

After seeing that I dont blame any rest asking for a credit card up front. THE FOOD AND SERVICE WAS GREAT.............
