Happy haunts, Kayra! Thanks so much for dropping in with your question.
I'm excited to hear you will get to attend this year's
Oogie Boogie Bash - A Disney Halloween Party! I am excited to be able to attend it too for the first time in just a few days. I took a look at the
Costume Guidelines for the special event, and it does not explicitly say that you cannot wear face paint. It only states that you cannot wear costume masks if you are older than 14 years of age. I recommend giving the guidelines a look yourself to familiarize yourself with them. Please note that a Cast Member could refuse entry into the parks if a costume violates any regulations and cannot be modified to meet them.
As a reminder, the event officially starts at 6:00 p.m., but you are allowed to start entering Disney California Adventure Park starting at 3:00 p.m., for the mix-in portion of the afternoon. Be sure to save plenty of room in your belly for all the candy from the treat trails and all the exclusive event food and snacks that will be available during the event.
Kayra, thanks again for visiting us here at planDisney. See you real soon!
Carrie
