We got back yesterday from a 9 night trip to WDW. We stayed 9/1 thru 9/10 and stayed at POR. I have to say, I have Never seen the parks so empty. The crowds were non-existent. We went to dinner this past Sunday and Monday night to Epcot. Walking around the world both those nights were unbelievable, there were so few people. I have never seen a park that empty in my life. AK, MK and HS were also very slow on the days we were there. We have gone the last 8 previous years, always the end of Sept, Oct or Nov and by far this was the slowest time. The only thing I might change is to skip AK if we go again in Sept. It was just too hot and no where to cool off. I felt like I was going to pass out, you literally felt like we were being cooked walking around. We had a great trip.
