The tours on quayside are brilliant, we have been doing it for years, they take you where ever you want, usually minibus, and you don,t pay until they pick you up. To give you some idea, in Barbados we got off the ship, crossed the road to bus stop, ($ 1 at the time) to go to a particular part of the island, others who paid the ships "beach" tour cost $40. Always use local transport, much ,much cheaper than ship.....and safe
