Hi Lisa!
Thank you for bringing your question to the Disney Parks Moms Panel!
Mickey's Not-So-Scary Halloween Party is such a great event. It offers so many unique entertainment events. Of those, the
Hocus Pocus Villain Spelltacular is a stage show that takes place on Main Street, U.S.A., in front of Cinderella Castle. This show is an exclusive event to the party. To attend
Mickey's Not-So-Scary Halloween Party, all Guests must purchase a party ticket that is separate from regular theme park tickets.
In addition to the Hocus Pocus stage show, party-goers can also enjoy the "Boo-To-You" Halloween Parade (best parade ever, in my opinion), the Happy Hallowishes Fireworks Show, iconic Disney character meets, trick-or-treating, dance parties and so much more! I highly recommend going to the party if you are there when they are offered.
I hope this helps! Please let me know if you have any other questions.
