For the 2026 season, Disney California Adventure (where Grad Nite is primarily held) typically closes to the general public at 9:00 PM on event nights. The private Grad Nite party then runs from 9:00 PM until 2:00 AM. It is important to distinguish between the "private party" and the "all-day" experience. Students with a "Park Hopper" or "Grad Nite Plus" ticket can enter the parks as early as 8:00 AM, but the exclusive "after-hours" festivities start once the regular guests are cleared out. At Walt Disney World in Florida, Grad Nite has largely been replaced by "Disney After Hours" or private group events, which also typically see park closures around 9:00 PM or 10:00 PM for regular ticket holders. If you are a standard guest planning a trip in May or June 2026, always check the "Park Hours" calendar 60 days in advance, as these dates are often blocked out for high school seniors, significantly shortening the time available for the general public to enjoy the attractions.
