Hawks Cay Resort

Hawks Cay Resort

10/10 Excellent
"The resort was beautiful. The food was good but pricey. We loved having the option to have the food/drinks delivered by the pool. The bed was comfortable and the Cabana room was very convenient to have right next to the adult pool area. Our only issue was the AC fluctuated a bit and a few nights it got too cold (one of our neighbors room was way too warm so it could have been worse). And the hot water wasn't really hot enough to take a decent shower. But overall we felt these were minor issues and the staff was so amazing we felt well taken care of otherwise."
