I too just got back from my trip. July 12 thru July 20. Yes, it was hot and humid, but never ventured out of the 90's. Back home in Oklahoma, my husband reported having temps. 105 and above. Their lows in Oklahoma were the highs in Florida during my trip.
The tour groups were still there the time that I was there as well. I stayed at the ASMu and it wasn't too bad there except when you're following them going to the food court or busses. They walk in lines like four across. There were more than one group there. One of the Brsazillian groups were very mannerly and orderly, another of the Brazillian groups were louder and fiesty. I had scheduled ADR at the Crystal Palace. I went solo, so I was easy to place. Low and behold, two of the tour groups came in about fifteen min. after me, and were seated right next to me. They had a party of 90. It got so loud, and the line was so long, I left without eating much at all.
I found the early morning times best for getting on rides easily. I was at MK on opening and before 10:00 AM I had ridden Pirates of Carb. BuzzLightyear, Winnie the Pooh, Space Mountain and was at rope drop to Toon Town. Walked streight up in the Charecter lines. Went from Toontown to see CinderellaCellebration, then right into Belle's storytime.
Now the park was really hopping the evening that I went and the Pirates ride was an hour and 50 min. wait. Very crowded.
I did the same simular thing at AK, went early and by 11:00AM I had ridden Everest, Dinosour, It's Tough to be a Bug, seen Lion King and did the Camp Minnie Mickey Minnie, and was on the bus back to the resort because the heat was coming on strong.
