I'm not sure what the heat and humidity are like in Iowa, but don't under estimate it here in Florida. Sun screen, long sleeved swim shirts, hats, and beach umbrellas or other shade is essential. The water and sand reflect the sun and you will burn even in the shade. Water for staying hydrated is also important. Your A/C may not cool like you expect, depending on how many units you have. I'm not saying you won't have fun, but the sun and sand will wear you out! Have fun and keep everyone safe.
