Hi Isabella!
I was so excited to see your question because I also love Halloween at Walt Disney World, especially when I walk into
 Disney's Magic Kingdom and see the Mickey Mouse pumpkins, bright yellow and orange leaves, and fun decor! 
Last year, the 
Disney After Hours Boo Bash was so much fun! This event had character cavalcades, trick or treating, and yummy treats. As you may know, prior to the Boo Bash, Mickey's Not So Scary Halloween Party was the signature Halloween event! The Halloween events have not yet been announced for 2022, but I am so excited to hear what is coming this year! Typically the special Halloween events are announced in early May, so I am hopeful that we will find out soon. 
Keep an eye on the 
Disney Parks Blog for updates on the Halloween events! During the 
fall, you can also enjoy the 
EPCOT International Food & Wine Festival! I love the outdoor kitchens and 
global marketplaces around the World Showcase. 
I hope you have a magical vacation!
Magically,
Stacy
