We were there from the 15-23 this past August. I don't think I'll be trying this time period again. I was prepared for the heat/humidity. I knew it would rain every afternoon. But....not rain/huge thunderstorms every day for the entire afternoon and most of the evening!!! Yes, I know, that's really unusual. But, when you are spending that kind of money, you want to be able to go to the parks or swim in the resort pool. The pools were closed a lot due to the storms. And yes. The storms were way out of the ordinary. The crowds were impacted by the weather. The parks were pretty crowded during the day. I'm sure the FTP worked as far as Disney is concerned. But, when the parks such as MK have to shut down rides due to weather it does make the crowds much heavier at the rides that are open.
Nope. We'll be traveling after Thanksgiving or mid-June or early March from now on.
