Hey there, Kelly!
Thanks so much for bringing your great question to the Disney Parks Moms Panel. I can't wait for you to experience the Disneyland Resort during my favorite season,
Halloween Time!
World of Color is my very favorite Disney nighttime spectacular, so I can see why you are so excited to see this fantastic show. During Halloween Time, normal World of Color performance schedules may be affected due to
Oogie Boogie Bash - A Disney Halloween Party happening on select nights at Disney California Adventure Park. The good news is that this party brings a whole new version of World of Color just for the Halloween season called Villainous. It will showcase famous Disney villains while bringing the sights, sounds, music, and pyrotechnics similar to the original World of Color that we all love. The only way to see these performances, though, is to purchase a party ticket which is separate from normal admission. There are going to be SO many new and exciting experiences happening during the party like trick-or-treating, new entertainment, the Frightfully Fun Parade, and plenty of unique Character experiences. I would highly recommend checking it out during your trip dates and purchasing tickets soon as they may sell out closer to your trip.
I hope this helps, and please return if you have any more questions. I hope your trip is spooktacular!
