Hey there Gretchen,
Welcome to planDisney! I'm so glad you stopped by with your question and am happy to hear that you're planning a trip to the Happiest Place on Earth during the
Halloween season.
I was able to experience the Oogie Boogie Bash - A Disney Halloween Party for the first time last year with my son and it was incredible. We had so much fun at all the character meet-and-greets and ended up with so much candy!
Typically, tickets for this event go on sale in mid-to-late summer. From what I've seen the last few years, they tend to sell out fairly quickly, so I would recommend having a couple of date options in mind if your travel plans are flexible. Similarly, I'd plan on logging on to the ticket purchase page first thing in the morning on the day they go on sale - otherwise, you might miss them!
The best place to find out when they'll go on sale is the
Disney Parks Blog and the special event page for the
Oogie Boogie Bash. Once tickets are planned to go on sale, either of these pages will have all the information that you'll need to plan your visit.
One other tip I'd share as you continue to plan your trip is to bring a backpack or bag to dump your extra candy! I visited with my little one, and while we each got a bag, it got pretty heavy for him, so it was really handy to be able to dump his candy into my backpack so he didn't have to carry it all.
Thanks again for your question, Gretchen! I hope you have a fantastic trip to the Disneyland Resort later this year.
Have a Magical Day,
Greg
