Hi, Julio!
What a fun time you have picked to visit. The weather is gorgeous and the Parks are wearing their Fall best.
While there is no special parade in any of the Parks, you might be interested in visiting
Mickey's Not-So-Scary Halloween Party, a separate-ticket even held at the Magic Kingdom on selected nights in October. The party will be happening both October 31 and November 1, and both of those nights are still indicating availability.
On Party nights, the Magic Kingdom will close at 7:00 PM to all of those who do not have the Party ticket. If you don't plan on attending the Party, you might want to consider going to a different Park that day. I'd suggest Epcot; the
Food and Wine Festival is still in full effect, and you'll get to enjoy Illuminations: Reflections of Earth, the amazing nighttime fireworks spectacular. Besides, at Epcot, you'll find Soarin' and Test Track and Journey into Imagination and so much more!
Have a great time!
See you later, celebrator!
