We recommend booking your tour as soon as you have your travel plans confirmed. Our tours can book up weeks in advance, so waiting until you arrive on-island for most things lately (activities, restaurant reservations, car rentals, etc.) will leave you with minimal options. We have a 24-hour cancellation policy for any groups with 5 or less people, and for groups of 6 or more, it is a one-week cancellation policy. If you need to change or cancel your reservation in advance of that cancellation period, please call our office directly 808-335-0815 so we can assist with no charges. If you cancel within the cancellation period, you will be held to full charges. We recommend booking your boat tour early in your vacation window, that way if weather or other factors force us to cancel your tour at the last minute, than you may be able to reschedule for another day.
