You may make changes or cancellations to your reservations up to 48 hours prior to the trip without penalty. Afterward, all changes, cancellations, or no-shows will not be issued a refund unless the space is filled by another diver. If we are able to fill the space a full refund will be issued. If we are unable to fill the space we cannot issue a refund. The only exception to this policy will be if we receive a medical note from a local doctor for a treatment/exam which must have taken place within 48 hours of the check-in time of the missed dive. This does not waive the companion diver or snorkeler.
