From late August through October 31, Disneyland Resort brings in seasonal decor, costumes, snacks and entertainment to celebrate Halloween. Some attractions even undergo special transformations (and name changes) for the season with new storylines, soundtracks or sets, like Guardians of the Galaxy – Monsters After Dark in Disney California Adventure Park and Haunted Mansion Holiday in Disneyland Resort. There is an after-hours party in Disney California Adventure Park called Oogie Boogie Bash – A Disney Halloween Party that requires event specific tickets. From late August to November 2, Dia de Los Muertos is also recognized in both parks of Disneyland Resort.
