we just returned from a 7 day carnival victory cruise (jan 20-27, 08). we never use the cruise line for tours, etc. research the island to determine what you are interested in. look over what the cruise line offers and then when you go ashore, negotiate your own deal with the usual array of guides knowing what you want and what you are willing to pay. in st martin brooksie gives a great guided tour and has been doing so for many years. if you want, i have his contact info. warm regards, fair winds and following seas
