Hi Jessica and welcome to
planDisney! I'm so happy to know you have a plan to visit the Walt Disney World Resort this September! Thanks for sending us your question.
You can absolutely visit a different theme park with your three-day theme park tickets before you attend
Mickey's Not-So-Scary Halloween Party. Your special event ticket will give you access to the Magic Kingdom Park as early as 4 p.m., so you have plenty of time to enjoy the morning and early afternoon at EPCOT, Disney's Hollywood Studios or Disney's Animal Kingdom theme park.
There have been some fun new updates for this year's party! Mickey and Minnie will have brand new costumes and even more of our favorite villains will be joining the celebrations!
Mickey’s Boo-To-You Halloween Parade is also scheduled a full hour earlier, at 8:15 p.m.
Jessica, I hope I've been helpful. Please feel free to come back to see us if you have any more questions. It's always
our pleasure to help you with all the details of your next vacation!
Veronica
