Disney will celebrate the start of the summer season by keeping three theme parks open for 24 hours straight on May 24.

Disneyland and the adjoining California Adventure will stay open from 6 a.m. on May 24 to 6 a.m. May 25. The Magic Kingdom in Florida also will stay open all night.

The announcement was made Thursday night in Orlando by Walt Disney World President George Kalogridis. Disney did something similar in 2012 to celebrate leap year.
