Hi Shaun, welcome to planDisney!
Your ticket gives you
access to Magic Kingdom Park as early as 4:00 PM, with Mickey’s Not-So-Scary Halloween Party beginning at 7:00 PM. Unfortunately, you will not be allowed entry earlier for a dining reservation without a day ticket. If you’d really like to have your meal at that location, I recommend trying to modify your reservation to a time after 4:00 PM.
If you’re interested in Halloween-themed snacks, this
Disney Eats: Foodie Guide to Mickey’s Not-So-Scary Halloween Party 2023 is a master list of all the special treats available, including where they can be found and if they are available during regular park hours or during the party only.
Another option is to enjoy some Halloween-themed treats throughout Walt Disney World Resort. This is a great option if you are planning on spending the day at your Disney Resort hotel before spending a late night haunting Magic Kingdom Park. Check out this
Disney Eats: Foodie Guide to Early Halloween Treats at Walt Disney World Resort for all the Halloween offerings at Disney Springs and Disney Resort hotels.
I hope this was helpful, Shaun.
Come see me again at planDisney if you have any future questions!
Beware of hitchhiking ghosts,
Kaitlin
