If you want to travel to Disney during it's quieter season, now is the time to go. It may be busy through September because free dining was offered to guests booking stays in late August through September, but after that the parks are much more manageable until the holiday season arrives.
I've visited Disney in November and December and it's a great time to be there!
It can get very crowded the week of the actual holiday, but if you arrive before that, you'll be in for a real treat.
It may be a bit early to rave about Disney at Christmas but I definitely recommend it -- it's a wonderful time to visit!
Last December we spent 6 days in Disney to see our daughter's high school chorus perform in the Candlelight Processional in Epcot. This event is a must-see if you're in Disney during the holiday season. You can purchase a dinner package that includes priority seating and dinner at an Epcot restaurant. If you don't choose the dinner package, you'll want to get in line at least an hour before the performance is scheduled.
Epcot's Food and Wine Festival is also held during the fall season and offers guests the opportunity to taste samplings made by the Disney Chefs from various restaurants.
Another popular fall event is Mickey's Not-So-Scary Halloween Party which is held throughout October.
The parks have some shorter operating hours during this season but it's a nice opportunity to see and do other things such as visit resorts you haven't been to or dine at one of their restaurants.
