Hi Eliza,
Welcome to the Disney Parks Moms Panel and thank you for asking us a question, my fellow Canadian!
Mickey’s Not-So-Scary Halloween Party is one of my favourite Special Events at
Magic Kingdom Park. There’s something just so much fun about getting dressed up in Halloween costumes (that meet the event’s
costume guidelines) and then going trick or treating throughout the Park!
Because this is a Special Event, you need to purchase a separate
Special Event Ticket. These tickets can’t be bundled into a regular
Theme Park Ticket with a Park Hopper Option. If you want to visit any other Theme Parks during the day that you’ll be heading to the Party, or even if you want to visit Magic Kingdom Park before the Party starts, you’ll need to purchase separate admission.
I hope my answer helps you plan your visit to Walt Disney World Resort this Fall. Please don't hesitate to come back and see us if you have any other questions. We’re always happy to help!
Have a Magical Day,
Lynne
