Hi, Karina!
I'll be your (g)host for this question here at planDisney tonight, and it's a pleasure to welcome you to our planDisney (Haunted) Mansion!
I'm so glad you're considering going to the Disneyland Resort to attend
Oogie Boogie Bash. I love to
visit the Disneyland Resort in the Fall, and I bet you will love it too!
The party happens on select nights during the Fall. The first Oogie Boogie Bash will occur on September 6, and the last party will happen on October 31.
This page has a lot of details about the event: You enjoy Immersive Treat Trails, the beloved Frightfully Fun Parade, exclusive shows, unique character experiences, and much more!
It's also my pleasure to share that you won't need a park reservation if you have a ticket to attend Oogie Boogie Bash. You can also take advantage of early admission to
Disney California Adventure Park at 3:00 PM. This benefit is super handy if you want to enjoy attractions before the party so that you can enjoy the atmosphere after the party kicks in at 6:00 PM.
Now let's talk about tickets! If you're a
Magic Key Pass holder or a D23: The Official Disney Fan Club member, you will have access to a limited supply of tickets on June 28 (no earlier than 9 AM PT). If you're not among these two groups, you will be able to buy your tickets beginning June 30 (no earlier than 9 AM PT). Tickets will go on sale through this link, Karina. They usually sell fast, so don't forget to check your dates as soon as possible!
I hope this answer helps you plan a FANG-tastic adventure for October!
May the magic be with you,
Julie
