Disneyland was forced to shut its gates during its 24-hour "One More Disney Day" leap day celebration, after huge crowds descended upon the park.
With Disneyland remaining open from 6am on February 29 through to 6am on March 1, it appeared at first that crowds were heavy, but manageable. However, high volumes of guests began to arrive during the evening, eventually forcing the park to pronounce itself "full" at 9.30pm. It eventually reopened its gates at 2am.
The Chicago Tribune attributes the problems to large numbers of annual passholders arriving at Disneyland at the end of their working day. The result was long lines for most of the park's attractions, as well as queues of frustrated guests waiting at its entrance.
Guests were able to queue from 10pm on February 28 to gain entry to Disneyland during "One More Disney Day", with many taking the opportunity to attempt to experience every ride in the park during the 24-hour period. Walt Disney World's Magic Kingdom also remained open for 24-hours, although crowds were not quite as heavy as those at its sister park.
In previous years, Disney has run special promotions covering all of its US theme parks, such as the "Give a Day, Get a Day" volunteering programme from 2010, and a 2009 offer that enabled guests to enter the parks for free on their birthday.
