Hi, Julyla!
Welcome to the Disney Parks Moms Panel, and thanks for your great question. The Halloween season is one of my favorite times to visit the Disneyland Resort. I love all of the fall decor, the seasonal treats, and experiencing the Haunted Mansion Holiday attraction.
On evenings when
Mickey’s Halloween Party is offered at Disneyland Park, the park does close earlier than usual (in the mid- to late-afternoon) for Guests who have not purchased a ticket for the event. However, you will be able to enjoy the park as normal for the earlier part of the day. The tickets for Mickey’s Halloween Party grant admission only to Disneyland Park (where the event takes place) and are not valid for park entry until late-afternoon.
So, you can enjoy Disney California Adventure Park after Disneyland Park closes or purchase tickets for Mickey’s Halloween Party on one of the evenings of your visit. My family loves enjoying all of the “spooktacular” extras available during the party, like the Halloween Screams fireworks spectacular, treat stations and character meet and greet opportunities. Plus, everyone in the family--including the adults--may wear a costume!
I hope this helps, Julyla, and that you have a wonderfully pixie-dusted vacation. Please feel free to ask me any other questions you may have as you continue to plan.
Wishing you magic,
Courtney
