We stayed for two nights for a weekend getaway two summers ago. Note that this was before recent hurricanes. Hotel was clean with decent, new-looking furniture and had a relaxed atmosphere, not overly stuffy like some. The hotel has a good uncrowded section of beach, the view was nice from our room, except for the roof of the restaurant below. We enjoyed the pool and tiki bar area. There were a lot of families staying there.
For us, the relative novelty was seeing the sun set over the ocean since we can only see it rise on the east coast. Views of that were gorgeous!
I think the summer off-season rates are worth it but you'll end up paying too much to stay here in the winter, unless you are a golf enthusiast.
Pros: Great golf course, excellent fitness center, spa and spa facilities. Great shower products. Something about the scent of the products they used in the spa made me feel extremely pampered and very much like I was at a spa, even when I was back in the room shampooing the next day.
