We just got back and yes, it was really hot, but I too did not see any lines that were three hours wait. I think the really big issue is that we saw a ton of large (probably youth) groups, and they would stand in one line, increasing the wait in that line, and one of the adults would go over to another ride with everyone's cards and get the fast pass... sometimes hundreds of them.
We had a fast pass for test track, returnable at the same time as one of these huge groups, and went right at the start of the time, to make sure to beat out this group. Still, we kind of got stuck in the middle of it.
This was not something that we noticed when we were in Disney two years ago, almost at the same time. But what we did is sort of move quickly when we saw those groups coming! And at Animal Kingdom, first think in the AM, we were able to go on Dinosaur and the Rapids, with only a five minute wait. But when we ran over to the safari, it was already forty (HOT) minutes. (felt like three hours!!!
) Then we had to rush back to the rapids to get there in time for the end of our fast pass eligibility. We just made it. And I saw that the rapids had a 90 minute wait.
We went back to the hotel, to the pool in the middle of the day each day.
My parents... they would never come to Disney in the summer.
