We were there last October, and it was pretty crazy. However, I think we had a unique situation due to everyone canceling their trips in September (due to the hurricanes) and bein able to reschedule in October. Even the bus drivers mentioned that it was seriously busy. That said, I was also pretty surprised by the heat and humidity. We are from out west and am totally unused to weather like that. When we scheduled we thought we were late enough to miss this, but no. I would try to go closer to the end of October, but not over halloween, to minimize crowd and humidity/heat! We had a fabulous time and so will you!
