It looks like the 24 hour days at U.S. Disney parks are becoming an annual event. This year's festivities will take place from 6:00AM May 23rd to 6:00AM May 24th.
Disney has also announced a contest for a 7 day/6 night stay at both Disneyland and Disney World parks including seeing both coast's 24 hour events. As you can tell from the image above, you'll be able to enter by using the hashtag #DisneySideSweepsEntry on Twitter to enter. Anyone heading out to either park this year?
