While Mickey's Not-So-Scary Halloween Party officially begins at 7:00 PM, guests with a party ticket can enter Magic Kingdom as early as 4:00 PM. This "early entry" is a significant perk, as it gives you three extra hours of park time before the regular day guests are cleared out and the spooky festivities begin. Upon arrival at 4:00 PM, you will go through a dedicated turnstile where you receive your party wristband and a trick-or-treat bag. Most guests use this time to ride popular attractions that might close during the party or to grab an early dinner so they can focus entirely on the exclusive parades, fireworks, and candy trails once the clock strikes seven.
