For visitors arriving on a cruise, our tours are sold from the Tour Desks of the respective cruise lines.  Please contact your Cruise representative to book your tour. Our system is a high volume system and in most circumstances we are able to accommodate everyone who wishes to participate on the tour on a given day.  Should Your cruise line advise the tour is sold out, we recommend you contact us directly via phone or email so that we can review the demand for that day and if in fact there is availability we will communicate directly with your cruise line to ensure you are booked on the tour. In the meantime, safe travels and happy cruising.  We look forward to your visit to our beautiful twin islands and be sure to come Fly with us!
