We came out here from the other coast of Florida for a family vacation. We went to the park on July 2. First into the park. We bought a fun card to visit two parks for $95, and purchased quick queue pass for $20 each online. Parking was $25. Well worth every penny. You have a separate entrance and get to enter the queue immediately. The upgrades are more expensive at the park.
You can bring in (I think clear) water bottles, and snack. Maybe repacked food in your backpack. No coolers. We brought in water bottles, and just bought the food, which has been the same at all parks. Fried, and less than mediocre food, and expensive.
The park is small, older, but still so much fun. We love water parks so it's hard not to like it, but if you have been to other newer and bigger ones, you will be disappointed.
Overall, it was a fun day! It rained around 3. Make sure to find chairs with a big umbrella so you wait out the rain if you decide to stay. A lot of people leave after the first rain.
