Yes, Disney has operated its theme parks for continuous 24-hour periods on several special occasions, a tradition that began with the "One More Disney Day" event on February 29, 2012 (Leap Day). Both Disneyland in California and Magic Kingdom in Florida remained open from 6:00 AM on February 29 until 6:00 AM on March 1. Following this success, Disney held several other "all-nighter" events to kick off the summer season, such as the "Monstrous Summer" in 2013 and the "Rock Your Disney Side" in 2014. These 24-hour marathons were known for their high energy, pajamas-clad guests at 3:00 AM, and unique nighttime entertainment. However, in 2026, Disney has largely moved away from these full 24-hour days in favor of separately ticketed "After Hours" events and themed parties (like "Star Wars Nite" or "Sweethearts' Nite"), which typically run until 1:00 AM or 2:00 AM. These late-night events allow for better park maintenance windows while still satisfying the demand for late-night "Disney Magic" with significantly shorter wait times.
