Hi Nicole,
I think you're asking about one of my favorite events at Walt Disney World Resort, the spooktacular
Mickey's Not-So-Scary Halloween Party. The party begins at 7 pm in Magic Kingdom Park with not-so-scary fun for all. With a party ticket, you can enter the park as early as 4 pm even though the festivities won't begin until 7. I have attended the party several times and they are prompt about when they begin Character Greetings and Trick or Treat trails.
There are new must-do
additions to the party this year! Mad Tea Party, Space Mountain, and Pirates of the Caribbean each have new experiences to enjoy and Storybook Circus will host the Storybook Circus Disney Junior Jam. Plus don't miss two of my favorites,
Mickey's "Boo-to-You" Halloween Parade (the parade music is my ringtone for the month of October) and the Hocus Pocus Villain Spelltacular with the Sanderson Sisters.
I made my first visit to Disneyland Resort last summer and fell in love with the parks there. My next goal is to be able to visit during the fall so I can enjoy Mickey's Halloween Party. It sounds like an equally spooktacular time on the West Coast!
Wishing you happy planning and a magical vacation,
Amy H
