Hello Natasha, and welcome to the Disney Parks Moms Panel with a great question.
You are going to have a ghoulishly good time during
Mickey’s Not-So-Scary Halloween Party. Guests with tickets for just the party can enter the Magic Kingdom can enter as early as 4:00 p.m. When you arrive at the Magic Kingdom, you will see Cast Members directing party guests to wait in a special line. While you are waiting, they will scan your MagicBand and give you a special wristband to wear during the party. You will be asked to show this wristband several times during the evening, to make sure only party guests remain in the Magic Kingdom.
If you are using a regular theme park admission ticket to enter the Magic Kingdom prior to 4:00 p.m. you can check-in for the party, after you have dined at
Liberty Tree Tavern, but before 7:00 p.m. at Guest Services, where a Cast Member will scan your MagicBand and give you a wristband and special event park map. You are going to have a spooktacular time.
Happy Halloween,
Andrea
