As others have said, your plans are extremely unrealistic. I have stayed at Windsor hills many times and I can tell you it's not worthwhile to leave the parks for afternoon breaks. It will take a good hour to leave the park, get to the car, and drive back to the house. If your kids are anything like mine, as soon as they get into that pool there is no getting them out. You may have a really hard time getting them back to the park. We find it to be way too much time wasted traveling. Instead we stay at the park until we are tired then head back to the house for the night.
