It's a long way to go so why not visit them all? ......Wilba.
Hi there - all the islands are worth a visit, but if you like the beach here are some ideas - mambo beach - curacao, grand anse beach - grenada, reduit beach - st lucia, dickinsons bay - antigua, frigate bay or friars beach - st kitts, cane garden bay - tortola, malibu beach - barbados - have a wonderful holiday.
Visit all of them. They vary so much that each one has something different to offer.
Hawaythelads all the islands are worth a visit most just a group of us off ship get a taxi/mini bus much cheaper than ships tours however there are some that can only be booked through ship like train on st lucia check out ships tours at http://www.princess.com/pb/shorexDetails.do?subnav=true&voyageCode=C907&tourCode=&resType=C&departurePort=&noOfCruiseDays=&noOfTourDays=&travelOrder=&productCode=CBE140&departureDate=Mar+21%2C+2009&productDesc=Grand+Caribbean+Adventurer+14+Day+Roundtrip this will give you some ideas most of the beach trips can be had by taxi will see you there as we fly from glasgow for same cruise steve & linda.
