Ghostly greetings, Karen! Thanks for stopping by planDisney.
Your question could not have come at a more perfect time - I was at
Oogie Boogie Bash (OBB) on Sunday! You'll be happy to know that if you have entered California Adventure Park with a regular park admission and
theme park reservation that you can pick up your Oogie Boogie Bash event wristband inside the park and will not need to exit and reenter. The park wristband pickup is between Avengers Campus and Cars Land. A Cast Member will scan your ticket, take your picture, and give you your event wristband and treat bag. Easy, right?
Be sure to enter the
PhotoPass ID from your wristband into the Disneyland Mobile App to link all of your spooky, scary photographs from the party to your account. Photo downloads from the event are free with the cost of the admission ticket!
The OBB event map that comes with your treat bag is perfect for planning your strategy for the party. My family and I started from the back of the park, near Pixar Pier, and moved toward the front. We found this was the perfect way to hit all of the treat trails!
I hope this information helps, Karen. Please come back with any other questions, and happy haunting!
Frightfully yours,
Melissa
