I enjoy the water parks, but I don't really consider going to them a break from the parks. In fact, we didn't even have the desire to go this past trip, and I don't think we will this time either. To really have a break away from the crowds and chaos, I prefer to head back to the resort for a nap and swim. Definetly try the water parks though if you haven't already, but as the previous poster said, make sure you are there early--once the crowds come it is really impossible to get anything done.
