Hello Hope,
Thank you for bringing your question to us here at the Disney Parks Moms Panel, we are here to help.
I'm thrilled you are visiting the Disneyland Resort during Halloween Time. Mickey's Halloween Party at Disneyland Park is a must-do, you are sure to have a spook-tacular time! "Be Prepared" to see Disney Villains throughout the evening. You'll also have the opportunity to Trick or Treat in Disneyland Park, enjoy the ghoulish "Halloween Screams" fireworks, and of course enjoy the holiday attraction overlay of The Haunted Mansion and Space Mountain, and much more! Be sure to watch "Mickey's Costume Party" cavalcade because just prior to the parade the Frozen stars will appear to melt your hearts.
Kids of all ages may dress in costume for
Mickey's Halloween Party. My husband and I cannot wait to show our Disney Side in Disneyland Park during Mickey's Halloween Party! Please ensure your husband that there will be a lot of Adults wearing costumes too. All Guests attending the party should wear child-friendly costumes. Remember, you may enter Disneyland Park three hours before the party starts using your Mickey's Halloween Party ticket.
I hope this helps and that you all have a Boo-tastic time. If you have any more questions, please feel free to ask me, I'm here to help you plan your magical vacation!
Wishing you 999 Happy Haunts!
