November is very much off-season for Disney - Christmas Crowds begin in mid-December and then drop off again shortly after New Years. The one variable this year is that the FantasyLand extension was scheduled for October, but crowds will still be far less than the Christmas Invasion that starts the second week of December.
As someone who worked at "Mouse-chwitz" for a year (developing websites in the "Hot Set" next to Toy Story Mania), I can heartily tell you that September - November, and January - March are the times to visit. The crowds are minimal, the temperature is great, and the cast that sticks around is experienced. If you are doing the water parks, November is better, because they close for cleaning in February and March (one at a time, for several weeks.)
If you want exact times, there are several free Disney World apps that show actual wait times at attractions. Disney itself holds on to these same data very tightly, so you'll need to go with the third party apps to see it.
