When I worked at Wild Wing Plantation in Myrtle Beach, we didn't have water coolers on the course. Instead, we had small coolers on all of our carts which we would stock with 6 small 8 oz. bottles of water and ice before each cart went out, and of course, our rangers would have extra water when needed. We had a deal with Coke and they would bring us pallets of the small bottles. Obviously, it is a cost you would have to offset but we certainly got a lot of compliments on it, especially in the summer months.
