The only reason we go to GA is because our kids get free tickets as part of a reading program in school. That saves a boat load of cash. We pack a lot of ice and have a sandwich lunch. We will go out, put on our swimsuits, eat lunch at the car, go to the water park for a few hours. Then we come back to the car, change, and then we'll eat something on the grounds. It is really expensive, though. I wouldn't go if the kids didn't go -- and it was free for them.
