Hi there Kaylene, welcome to planDisney!
Oogie Boogie Bash will take place on select dates at
Disney California Adventure Park in September and October, and the park will close early at 6:00 PM on those event days. You can reference the
Hours & Events Calendar to see the daily schedule so you can plan accordingly for those dates.
My first recommendation would be to make a
theme park reservation for
Disneyland Park on days where Oogie Boogie Bash will be taking place at Disney California Adventure Park. The park will not close early and you'll still be able to enjoy the
Halloween Time festivities such as the
Halloween Screams nighttime spectacular!
You also could upgrade your theme park ticket to a
Park Hopper ticket if you haven't already. That way, even if you start your day in Disney California Adventure Park, you can make your way over to Disneyland Park later that day when Oogie Boogie Bash is about to begin. It's so easy and convenient to park hop between both parks that I always recommend upgrading to a Park Hopper ticket!
I hope this information is helpful for your upcoming trip Kaylene! Wishing you and your family a spooktacular visit, and if we can help with anything else, please
come back to planDisney!
Have a magical day!
Melissa
