Hello there Marian,
Welcome to planDisney and thank you for your question! I'm thrilled to hear that you're headed for the Disneyland Resort in just a few weeks. You're going to have such a great time!
I'm happy to share that you absolutely can attend the
Mickey's Trick and Treat Halloween Party at Disney California Adventure Park. This is a really fun show, especially for little ones, that is Halloween themed and replaces the
Disney Junior Dance Party during the Halloween season. There are various show times throughout the day, so make sure to check the Disneyland Resort mobile app to find a time that works best for your schedule.
There are so many other fun things to do at the Happiest Place on Earth during the Halloween season as well. I'm a huge fan of the other attractions that get a fun Halloween theme during this time of year including
Haunted Mansion Holiday,
Guardians of the Galaxy - Monsters After Dark,
Mater's Graveyard JamBOOree, and
Luigi's Honkin' Haul-O-Ween.
You can also get pictures with some of your favorite characters in their
Halloween costumes and enjoy special Halloween-themed treats around the park! You can get a great overview of the food and beverage options with the
Foodie Guide on the Disney Parks Blog.
Thanks again for your question, Marian! I hope you have a spooky fun time during your visit.
Have a Magical Day,
Greg
