Have cruised with RCI and they usually have a good selection of tours to choose from but as with most cruise lines they are a bit over priced and where possible it is best to find your own way about or find someone to share a cab.
RCI usually do offer shuttle buses to the main town when they port out of the main tourist area but they usually charge for these also. I have been to the carribean before but not with RCI. Most ports of call in the carribean are usally not far from the main places but without knowing your ports of call can't realy help with recommending where to go.
Hello! We went RCI some years ago, We love wildlife (and a bit of fun) Barbados (Jolly Roger!) Fun bit. Grand Cayman! Been to Hell and back! Turtle Farm, great excursion, also the Stingrays! Mexico Tulum Ruins (we think we've got it bad!) Jamaica! would not do any excursions ever again there! Dead dogs all over the place, really upset us, also constant pestering to buy 'Ganja' etc. Many other beautiful Islands(Also nudist beaches (which were an eye opener!) Especially where some of the body piercing was! Sure you will enjoy it no matter where you go! It all adds to the experience of life.
