Don't worry, you can still dress up.
Mickey's Halloween Party is retiring to Florida. Disneyland's wholesome, long-running, kid-focused, trick-or-treating event was a favorite for Disney fans (of all ages, we don't judge) who were allowed to go to the parks IN COSTUME, which is normally against the rules. This year, Disney is replacing the SoCal event with something slightly more sinister: the Oogie Boogie Bash, themed around Nightmare Before Christmas villain Oogie Boogie. It's also switching parks, with the monster taking over California Adventure. It's a darker take on Halloween, with a focus on villains, and a storyline that involves Oogie Boogie casting a spell to take over the park.
