Apparently, Disneyland (and I assume DCA) will be open 24 hours on May 24. We were (are?) planning to be there that day but will not be all-nighters. Can anyone offer tips from the last time this occurred (Feb 29, 2012, I believe)? Is the park crowded most of the day or do the crowds come late? Are the crowds a nightmare? I assume the crowds will be much greater this time than last year since it's Grad night, May, Memorial Day weekend, etc. Any insight is appreciated.
