This same thing happened to us many times for our September trip. I mean right up to just a couple of days before arriving. They closed the water parks EACH 2 days a week, then openned one on a Saturday it was suppose to be closed. It was crazy. So when I see folks get excited about the park hours being posted, I tend to take a cautious approach to making my plans. We leave in a couple of weeks, so never know what further changes will occur.
