The Happiest Place On Earth turns into the Most Crowded Place On Earth: two videos showing crazy Disneyland crowds at 12:42 am on Main Street. FYI, Disneyland stayed open 24 hours from 6:00 am 2/29/2012 to 6:00 am 3/1/2012 to celebrate Leap Day. Crowds were so large that Disneyland had to shut its gates for several hours. Our prayers go out to all the employees!
