No, an Oogie Boogie Bash ticket is specifically for Disney California Adventure Park, not Disneyland Park. This after-hours event is a "separately ticketed" Halloween party that takes place on select nights in August, September, and October. In 2026, a party ticket typically grants you entry to Disney California Adventure as early as 3:00 PM, allowing for three hours of "mix-in" time with daytime guests before the official party begins at 6:00 PM. If you wish to visit Disneyland Park on the same day, you must purchase a separate standard theme park admission and make a reservation for that park. Because Oogie Boogie Bash is an exclusive, limited-capacity event, it features unique character sightings, treat trails, and the "Frightfully Fun Parade," but all of these experiences are confined to the California Adventure side of the resort.
