We just returned from a trip August 29th to September 6th. We had never been this time of year either. We usually go in November and had been once in March. Turns out, we loved it! We are from South Texas so the heat did not bother us too much. It did rain a few days in the late afternoon and once in the evening, but nothing that lasted very long. The crowds were much, much lighter than we are used to in November, although the crowd calendar numbers were the same. I'm not sure if the crowds were so low due to the fact that people thought Hurricane Erika was coming in or if it's always that slow this time of year. Most days we would take a mid-day break and go to the pool. We took off a couple of days. Don't know if you are doing the water parks, but we also went to Blizzard Beach, which the first time we have done a water park. We really enjoyed that. Overall, due to the low crowd levels, I think we will probably make late August/early September our preferred time to go to Disney! Enjoy your trip!
