Well we will use the dive shops for tank rentals and odd and end stuff. The boat rental place provides maps with GPS coordinates for all the dive spots. A friend of mine is covering the cost of the boat rental because Im paying for his flight from Scotland. We will dive where we want to when we want to. Dive shops are close to the Villa or right on the water. We will most likely rent a few tanks at a time to keep from having to go back to the dive shops all the time.
