Hey there Lachlan,
Welcome to planDisney and thank you for your question! I'm thrilled to hear you got tickets for
Oogie Boogie Bash - A Disney Halloween Party. I was able to attend last year for the first time and it was incredible - I'm sure you're going to have a blast!
It sounds like you've got a really smart plan here. If I'm understanding you correctly, you've purchased a standard
theme park ticket and set your
theme park reservation for
Disneyland Park. You'll plan on visiting Disneyland Park and experiencing all the fun for the day.
Then, since you have your special event tickets, you'll have access
Disney California Adventure Park starting at 3:00 PM that afternoon so you can head into that park whenever you'd like after that time to enjoy the event.
Since you already have your theme park tickets and park reservation for Disneyland Park for the day, you'll be able to head back into that park up until it closes in the evening, which you'll be able to check on the
Hours & Events Calendar page about six weeks prior to your visit. That all sounds like it checks out to me!
That's a great idea, Lachlan! Thanks again for your question and I hope you have a great time at Oogie Boogie Bash - A Disney Halloween Party.
Have a Magical Day,
Greg
