I also recommend CYOA for all the reasons mentioned (as well as they manage my boat). The other key advantage is that they are centrally located between SVI to the west and St John/BVI to the east as compared to starting from PR. This allows you to much more easily adjust your sailing itinerary to the weather conditions - head to the generally more exposed SVI if the conditions are favorable or to the generally more protected St John/BVI area if you get days with 20+ kt winds or heavy north swell.
