Hi Kanoe! Thanks for bringing your question to planDisney.
Oogie Boogie Bash - a Disney Halloween Party is a popular seasonal event that often sells out. While some dates are still available for purchase, your preferred
party date has filled up. While it certainly wouldn't hurt to ask a friendly Cast Member once you arrive whether there's a ticket available for purchase for your additional Guest, I wouldn't count on it. Unfortunately, there are no tickets held back to be sold closer to a party night, and since party tickets are non-refundable, new tickets don't become available. I'm sorry if that's not the news you were hoping for today!
If some in your group have party tickets and one person doesn't, I'd make some magical solo plans for that night. I actually really love exploring the park solo! You can do exactly what your heart calls you to do! Disneyland Park will be open during
regular park hours, so your Guest can enjoy Attractions, make solo
dining reservations, and find the perfect spot for one for evening entertainment. Plus, the
Downtown Disney District has plenty to experience as well, which doesn't require an admission ticket if your Guest doesn't have one for the day. And don't worry, there's plenty of seasonal decor and snacks to get you in the spirit in Disneyland Park and the Downtown Disney District even without access to the party.
If your Guest has a
Park Hopper ticket, they can spend time with you in Disney California Adventure Park until the party begins, then hop over to Disneyland Park for their night of fun. Guests with party tickets can enter Disney California Adventure Park starting at 3 PM, which is a great added benefit!
I hope this helps.
Elizabeth
