The one at bcv is sort of small. If you walk from the quiet pool down by the "dunes" towards the main beach club entrance you'll pass it. There are a couple of benches and a grill.
At wilderness lodge, it is down by the boat rental docks.
At kidani it is incredible, there is a pavilion by the basketball court with several picnic tables, three or four grills, garbage and recycling, and a water spicket. And ceiling fans!
