I was talking to somebody today that said they tried to add the dining plan at check in and they were told they couldn't do it. They had to add it 48 hours before check in or they couldn't have it. Is this true?
For a WDW package reservation it must be done at least 72 hours prior to arrival, not 48. 48 hours is only for DVC reservations. Whichever reservation is involved, it is true DDP cannot be added at check-in.
