Great private location scenic views overall I would go back again but probably stay in the newer section

Liked:The property grounds were real nice good beach location very private two swimming pools a great tiki bar by one of them nice hot tub great views also a nice rooftop bar and restaurant

Disliked:We stayed in the older part of the resort which was a little dated but it was fine could use a little maintenance stupid things like paint and lightbulbs but overall it was fine if all you were looking for was a place to sleep but again that was the old section I think the newer section and the rooms that were right on the ocean looked a lot nicer

Beach restoration ruined the experience

Liked:We were so excited about staying at this property based on the outstanding reviews. The experience was ruined by the beach restoration. The smell and noise made it impossible to enjoy our balcony, beach or pool area during our entire stay. I understand that improvements need to be made, but am disappointed that I wasn’t notified this would be going on during our stay. (I made the reservation over the phone) If we would have been informed, we might have made a different lodging decision.
