We went the first week in August last year and we did not see any tour groups. We had sort of strange experiences with crowds. There were a lot of people there, however we did not wait long to get on many rides, like 15 minutes for HM and 10 minutes for PotC. And we used Fast Pass when we needed which also worked out great. We also had no problem finding tables for counter service restaurants. We did avoid which ever park had EMH for that day. So while walking around, the parks really looked jammed packed, however it seemed that no one was riding anything or eating and just walking around aimlessly I guess. :shrug: We just found that sort of strange. Have a great trip. Oh, and I also want to add that I was never so hot in my entire life than during that trip and we had a lot of rain.
