Via a Disney Parks Blog announcement, Disney confirmed the return of the popular 24-hour day over Memorial Day Weekend, beginning at 6am on Friday May 22nd and ending at 6am on Saturday May 23rd. It’s a strange promotion because Memorial Day Weekend is already naturally crowded and the long operating hours stress out cast members that are already looking forward to an excruciatingly hot, busy summer season. This year, Disney’s Tomorrowland movie will open on the 22nd, but the in-Park tie-in remains Olaf and Frozen.
Anyway, the novelty of these events is the late night, with peak crowds from 7pm-1am. Expect daytime crowds from 6am-6pm on Friday to be manageable should you already have plans to visit Magic Kingdom. By 8pm or so, Magic Kingdom’s parking lot should close to capacity with guests sent to Epcot to park and then take the monorail over. I’ve attended the event the last three years and never had any problems before 6pm on Friday. After that, it’s a fun atmosphere that isn’t really replicated any other day of the year. But it is hot, humid, and crowded after 8pm with more people in the Park than the wait times might indicate.

The announcement should have a mild impact on the crowd calendar for that weekend. Magic Kingdom will remain recommended on Friday the 22nd through 6pm. After that, it’s going to be crowded and potentially difficult to park. Saturday should remain non-recommended due to the holiday, but you would be able to have a lot of success from 9am-12pm, not unlike any other day. It also looks like Disney is canceling the evening Extra Magic Hours on Saturday the 24th, though that is not yet confirmed.
