Hello there Raymond, welcome to planDisney!
How exciting that you were able to secure
Oogie Boogie Bash tickets! I always get so excited to see what Disney villains will be wandering around
Disney California Adventure Park and throughout the
treat trails.
One of the best things about Oogie Boogie Bash is that everyone can dress up and wear a costume! It does not have to be a Disney character, but there are specific
costume guidelines for special events that you'll want to review prior to your arrival. If you have more specific questions about your costume, I'd reach out to the
Guest Services line, or begin a chat with a Cast Member in the
Disneyland app.
One tip I recommend for having a spooktacular time at Oogie Boogie Bash is arriving as soon as the "mix-in time" begins which is at 3:00 PM. You'll be able to enter Disney California Adventure Park before the party actually begins, and the party will officially begin at 6:00 PM. You can map out your plan for the party, and grab some food so you can just enjoy the party when it begins. I also highly recommend getting in line early if there are specific characters you'd like to get photos with. The more popular character lines can get extremely busy, so you'll want to get in line for those early in the evening.
I'm wishing you a frightfully good time during your trip Raymond, and if you have any other questions, please do not hesitate to
come back and ask!
Have a magical day!
Melissa
