I am sorry, but I think you are being a bit "over cautious". The excursions can be had for about 1/2 of what the ship may charge. They are all government controlled & they DO depend on the tourist for their livlihood! They do not want to mess up their "goldmine." They are all very responsible (Jamaica excepted), reliable, & always on time. We have been on over 10 cruises in the Caribbean & have NEVER had one iota of a hint of a problem. Go & enjoy - & RELAX!!!
