Hey, Malissa, and welcome to planDisney.
Mickey’s Not-So-Scary Halloween Party is when all the ghoulish delights are seen and the sweet ones conjured up in the
Sanderson Sisters' cauldron. Great ready for a hauntingly happy evening staring Mickey and his all-star cast including epic Disney villains.
Since you may enter
Magic Kingdom Park at 4:00 pm with your party ticket you may not want to put your costume on just yet.
Locker rentals are to the right side of the entrance plaza after you pass through the touchpoints and before you go under the train station. Prices for lockers range from $10-$15 per day (prices subject to change) and are available till one hour after the theme park closes. That is plenty of time to enjoy the treat trails and have a spot to store your candy haul.
planDisney Pro Tip: Locker rentals are perfect spots to store your souvenirs and party merchandise so you do not have to carry them around all evening.
Malissa, I hope your trip below the 40th parallel is eerily spell-tacular. Please
write me back directly with any follow-up questions.
Enjoy making many Magical Memories.
