What special event celebrates Disney characters during the fall at Disneyland?

The event that celebrates Disney characters during the fall at Disneyland is Halloween Time. This seasonal event typically runs from mid-September through early November and features Halloween-themed decorations, attractions, and character experiences. During Halloween Time, guests can enjoy the transformation of attractions like Haunted Mansion into a themed version called Haunted Mansion Holiday, which merges the spooky season with elements from "The Nightmare Before Christmas." Additionally, special character meet-and-greets take place, allowing guests to interact with Disney villains and other characters dressed in festive attire.

The other options, while they represent different celebrations, do not specifically focus on Disney characters during the fall. Christmas in Disneyland celebrates the winter holiday, the Fall Festival might suggest a more general autumn theme without the specific Disney character focus, and the Spring Spectacular occurs in a different season altogether. Therefore, Halloween Time is uniquely characterized by its celebration of Halloween themes alongside beloved Disney characters.
