If you’re dreaming of spending Halloween at Walt Disney World or Disneyland, the time to start planning is now. Disney’s Halloween festivities—including Mickey’s Not-So-Scary Halloween Party in Florida and Oogie Boogie Bash in California—are some of the most popular seasonal events of the year, and they sell out quickly, often weeks or even months in advance. Tickets typically go on sale in early summer, and the earlier dates in September tend to be more affordable and less crowded. In addition to special parades, exclusive character meet-and-greets, and themed treats, many guests dress up in costume and enjoy park-wide spooky décor. Booking your tickets, park reservations, and hotel accommodations well in advance ensures you don’t miss out on the magic. Whether you’re planning a family getaway or a festive adults-only trip, Halloween at Disney is an unforgettable experience—but only if you plan early.
