Hello. We are arriving on a cruise on the 17th, and we are interested in doing the Sting Ray tour and if possible swimming with the turtles. Along the way, we would like to see some of the island's highlights. Not sure if we are asking for too much. What would you suggest, and how can we go about organizing this? I have contacted a couple of cruise companies that do the sting ray tour and that seems easy enough. HELP!
