Nope. Lots of ghouls and ghosts running around.
About Costumes: Guests, both children and adults, are welcome to wear costumes, but costumes are not require to participate in or attend Mickey’s Not-So-Scary-Halloween Party. About half of those attending will dress up. Although Mickey’s Not-So-Scary-Halloween party is the one time of year Disney relaxes rules about costumes in the park for anyone over the age of 9, there are a few rules that must be followed.
• Costumes must not obstruct vision or drag on the ground.
• Costumes with sharp or pointed objects, large props or items that can be mistaken for actual weapons are prohibited.
• Those dressed in Disney costumes may not pose for photos or sign character autographs.
• Use good judgment when selecting costumes. Disney may ask those with costumes deemed offensive to other guests to remove the costume or exit the park.
Lastly, if you’re going to dress up, remember that the weather can be quite hot and humid in Florida during both September & October. Try to choose a light-weight costume that doesn’t require a stuffy overcoat, mask, wig, etc. You’ll be glad that you did. Also be sure to check the Orlando weather a few days before your visit. The party goes on rain or shine, you’ll want to be prepared if rain is in the forecast.
