Hi Lindsay!
Thank you for bringing your question to the Disney Parks Moms Panel!
Mickey's Not-So-Scary Halloween Party is a wonderful event and the perfect way to start celebrating the fall/winter holiday months. The "Boo-To-You" Halloween Parade is, hands down, my favorite parade ever!
With unique-to-the event parades, stage shows, character meetings, photo opportunities, merchandise, themed food items and trick-or-treating, the party inside
Magic Kingdom Park is about a lot more than the attractions. In fact, I have been to the Halloween party before when I didn't ride a single ride! Because of this, every person (except children under three) who enters the park must have their own admission ticket. You can purchase
Mickey's Not-So-Scary Halloween Party tickets for your grandparents online or at the park entrance. Just keep in mind that many of the parties will sell out prior to the party date.
I hope this is helpful! Please let me know if you have any other questions as you plan your multi-generational trip.
