This resort truly exceeded my expectations with its stunning ocean views and beautifully maintained grounds that created a tropical paradise. I loved the spacious and comfortable rooms, which were perfect for my family. The diverse activities kept my kids entertained, and while the food quality was impressive, the prices were a bit on the higher side. The only downside was the beach area, which could use some cleanliness improvements, but overall, it provided a lovely atmosphere for sunbathing and swimming.
