DH asked me this. I am thinking the answer is no, but I'm curious. He has some friends going on the DDP next week and they have made no ADRs. If they find all the TS places booked are they just out of luck for a place to eat? It seems to me that most Disney visitors are not planners like us DISers. I'd personally be pissed if I paid my $39 a day for the DDP and found that I still had to shell out money for a meal because the restaurants were all booked.
