Hi Erin,
My family just loves Mickey's Not-So-Scary Halloween Party at the Magic Kingdom. Your children will love dressing up and seeing their favorite Disney Characters in costume and Trick-or-Treat around the Magic Kingdom! The party starts at 7:00 pm and will last until Midnight. There is a
Boo to You parade with the Headless Horseman riding down Main Street U.S.A. beginning this wonderful parade. There are also special
HalloWishes fireworks in the evening. I am not sure how long your children will be able to stay up but the Halloween Party is great fun!
Mickey's Backyard BBQ at Fort Wilderness Resort & Campground is an all you can eat Disney Character Dance party. You will have dinner with chicken, ribs, hot dogs, and corn on the cob to name a few items. If your kids love dancing, this will be a great time. It is limited time and won't go on all evening so this may be a great option as well. I don't think you can go wrong, Erin, in your choice. It will depend on how your kids do at night. I would tend to go to Mickey's Not-So-Scary Halloween Party because this is only during a few months out of the year, and it is one of my favorite events! I hope you have a magical vacation.
