Despite the very nice, spacious living rooms with bedrooms, my family struggled doing anything other than staying in the bedrooms while there. I should point out we were there in the middle of July. Each bedroom had its own portable air conditioner, which was adequate, but nothing, even leaving the bedrooms doors open while we were out, could help the heat downstairs. Without dedicated a/c, that space was essentially a complete waste to us.
The beach was about a 150 yard walk from there to the Sheraton public beach, 5 min drive to Poipu Beach, and a 10 minute drive to Shipwreck beach. There were several nice restaurants within a 5 minute drive.
