Disney announces another 24-hour party at Walt Disney World and Disneyland

February 28, 2014, 10:31 AM · The Disney Parks announced their third 24-hour theme park party this morning, a costume party that will take place between 6 a.m., May 23 and 6 a.m., May 24 at Walt Disney World and Disneyland.

The Magic Kingdom, Disneyland and Disney California Adventure will be open for those 24 hours, with guests invited to dress up as their favorite Disney heroes or villains for the "Rock Your Disney Side: 24-Hours" event.

Disney used 140 characters to announce the event. Literally.

From the official announcement:

The celebration on both coasts will feature a cavalcade of events showcasing the good-vs.-evil of classic Disney stories including character meet-and-greets throughout the parks, special entertainment, event merchandise and special food and beverage offerings.

Disney's also giving away a trip to the party. People who follow @waltdisneyworld and/or @disneyland on Twitter can enter by tweeting about "showing their Disney Side this summer" and including the hashtag #DisneySideSweepsEntry. The winner gets a trip for four to Walt Disney World, then to Disneyland, on May 20 through May 26, 2014. The trip includes three nights' hotel and a four-day park-hopper at each resort, plus one day with a tour guide on each coast. One tweet per Twitter account per day between now and March 31 will be considered for entry, and the winner will be selected randomly. The contest is open only to adults in the United States and Canada.
