I visit DLR and DCA every other week and last weekend IMHO was a bit more crowded than normal. I would suspect this was due to the Tinkerbell race (which I was participating in), hatbox ghost, and Mother's Day as well. I'll be staying at Grand California from May 21 to 24 and I would suspect it's going to be even worse considering the opening of the Diamond Celebration and the 24-hours of Disney Event. I'm just glad I can always runaway to the hotel if it's get to be too much.
