Well, we were there mid-August last year and planned on thunder showers every day. Yep, we had 'em but they lasted from 3 pm until late evening!! And they sure as heck weren't showers. More like torrential downpours. We were walking in 3" puddles at times. But, we had our ponchos so we kept on trekking. If it does thunder/lightning then the outdoor water rides are shut down. So, go prepared. I prefer the Mickey ponchos but my dh likes the disposeable .89 ones. They're too tight and clammy for me. Whatever you choose, be sure to carry them with you 24/7!!!! We didn't and we now own 3 sets of Mickey ponchos!!! Oh and by the way....we are going back in two weeks, so I guess it wasn't tooooo bad last year!!
