The room was outstanding. The view was absolutely gorgeous. We were on the same floor as the entertainment/bar, but the noise was minimal and stopped at a reasonable hour. Parking was convenient too.

Beautiful hotel. Nice view of the sunsets. Close by diner at resort . The only complaint is the floors were sandy when we didn’t even go in the sand . They should try leaving the room a broom and have rugs by the door . This would help immensely.
