We were there last weekend. The temp on Saturday morning was 62 F. We got there at 8:45 for the 9:00 early entry for hotel guests, and there were about 4 families waiting. We had the park to ourselves all morning. All rides were ride now! The water was warm, out of the water was very chilly but we warmed up quickly in the sun. It was about 70 F when we left at noon. Sunday morning, we did theme parks until lunch and then went to VB, it was about 70 F and we were fine. Again, the two rivers and the wave pool were warm, standing in line for slides was the worst, since it was windy. I'd say go for it, be prepared to bundle up in towels when you are out, but we are very glad we went! My kids had the run of the place, they will be in for a shock our next trip when they have to tap into slides!
