Hi Melissa,
I love the Walt Disney World Resort in the fall months-cooler temperatures (by Florida standards, and I'm a 32 year resident of the Sunshine State), much smaller crowds AND my favorite special event of the year,
Mickey's Not-So-Scary Halloween Party (MNSSHP)! I took a look at the Undercover Tourist Crowd calendar and low to moderate crowds are expected at the end of October.
One of the best things about MNSSHP is the very low crowd levels during party hours. There are a limited number of tickets and once they're sold out, that's it. What does this mean for you? Walking right on to nearly every attraction, plenty of viewing space for Mickey's "Boo to You" Halloween Parade, and incredible views of Happy HalloWishes, the nighttime fireworks spectacular during the party.
Melissa, I hope you and your family have a wonderful time at Mickey's Not-So-Scary Halloween Party!
Best Wishes,
Amy B.
