There are chairs with umbrellas available for rent on the beach. If I remember correctly, I think you can rent them from the lifeguard. The beach house has pool towels that you can take down to the beach.
Just got home from HH late yesterday afternoon. We rented an umbrella and two chairs for 2 days for $48.00.
Body boards are also available, but I'm not sure of the exact price on those. One day we rented two of them and it was $24.00, another day we rented one and it was $11.00.
