You can take water in but not sure about the small cooler.You can go to their website for more information.
Water is fine. They also say they allow small snacks. Not sure exactly what that means.
They have small lockers and you also have the choice to rent a cabana or umbrella...where you can take that too. I thought their package that included free drinks (including bottled water) and food all day was a good deal (considering the price of each meal).
