It’s unfortunate, but our system won’t let us display them on the calendar. When you click ‘Book / Details’, you’ll be able to see the departure and return times for each and every trip.

If a trip is sold out and you no longer can see the ‘Book / Details’ button, you may either look for any notification emails from us confirming your booking (invoice or reminder emails) or simply contact us.

Please note that the order in which the trips appear on this page may not match the order they’ll happen in real life (the ones on the top are not always the first trips of the day).

You must first get to the payment page. Create your booking as you would without a Gift Certificate. Once you get to the payment page, instead of adding a credit card, click on ‘Gift Certificate’ and copy your full code there. It should look like this: G482788-311-051820.

This 45-second video will show you exactly how it works.

Upon clicking on ‘Book / Details’, a popup screen with the date, time, and number of divers will be displayed. At the bottom of that screen, you’ll read ‘Click to apply a promo code’. Click that link and type in your promo code, then hit ‘Apply’. The code will be applied to the final balance automatically.
