Hi, Amy!
The time you mention - late October - early November - is a fabulous time to come visit. You're between holidays - Halloween attracts visitors to
Mickey's Not-So-Scary Halloween Party - and, of course, the kickoff to the Christmas season: Thanksgiving.
And because most children are still in school, you'll find the crowds to be manageable.
While the weather is still warm, it's by no means summer-hot. You'll be able to swim, certainly, but the "idea" of fall is just starting to enter the Florida air.
Fall specials are typically released in March or April. You might want to keep an eye on Disney's
Special Offers page; currently, there's a promotion for travel through mid-September.
Have a wonderful trip!
See you later, celebrator,
-Deborah B.
