We just got back and the weather on Saturday was pretty close to what they are calling for this week. In my opinion, it was a little cool for a waterpark. I would be ok at the resort pool where you could either stay in the water or lay out most of the time. But to be in and out of the water for slides and stuff, I would find it too cool. The Monday of Thanksgiving week it was definitely warm enough for a waterpark, but then a cold front came through and it got cold and then warmed up to seasonable. So you just really never know what you will get.
