Hey Amanda
Welcome to planDisney!
You’re going to love your trip to the Spookiest Place on Earth! October is such an awesome time to visit and you're going to be so glad you chose this time of year. Oogie Boogie and the rest of his pals can't wait to welcome you back to
Oogie Boogie Bash- A Disney Halloween Party! At this after hours event you’ll enjoy immersive treat trails, photo opportunities, entertainment like the Frightfully Fun Parade and Mickey’s Trick & Treat, attractions, ghoulish décor and so much more!
Avengers Campus will be available to explore during this fun after hours bash. You would be able to join the virtual queue at 7:00am but would more than likely not be able to ride it because those groups who join at the 7:00am time slot are usually called by noon and you would not be able to enter Disney California Adventure Park until 3:00pm. You would need to purchase a day ticket in order to enter the parks starting at opening.
Well Amanda, I hope you enjoy the party and have a spooktacular time!
Remember, always believe in the Magic!
Andres
