I was in Samana in Oct. 2007. Sailed on NCL Pearl and we were also advised to take an organized tour. Decided to visit Cayo La Vantido (sp?). Took a small boat to the private island area. It was amazing! Warm, blue water, lots of lounge chairs, fresh tropical drinks, massages on the beach. There were clean restroms and some local vendors. This is still one of my favorite excursions....and it was cheap, like $30 pp! Hope you have fun!
