Hi Amy and welcome to the Disney Parks Moms Panel!
I can understand why you would be interested in
Mickey's Not-So-Scary Halloween Party. It's my favorite
Special Event at Walt Disney World Resort. There is so much to see and experience plus it's fun to get dressed up! Unfortunately,
Disney Parks tickets are non-refundable and non-transferable.
I encourage you to think about using your park ticket to visit one of the other magical parks at Walt Disney World Resort during the day and purchasing a ticket for
Mickey's Not-So-Scary Halloween Party so you can enjoy the party.
My favorite part of Mickey's Not-So-Scary Halloween Party is
Mickey's "Boo-to-You" Halloween Parade. From the ride of the Headless Horseman to your favorite villains, everyone is ready for a spooktacular time!
I do recommend you call the Ticket Hotline (407) 566-4985 and explain your situation. There may be nothing they can do, but there is always a teensy-tiny chance they can do something.
Amy, thank you for visiting us with your question. Please let us know if we can help you with any other questions!
Wishing you a magical vacation,
Amy H.
