Activity name

We guarantee the lowest price on all the activities available to book on our site. We'll refund the difference if you find the exact activity cheaper online until 48 hours before your activity starts.

We Make It Easy!

Gather your information

Locate your Cool Hawaii Booking Number and the proof of the lower price you found.

Send it to us

Email [email protected] with the documents, your name, and your home address.

We'll review

We'll review your materials and get in touch as soon as possible.

If everything checks out, we'll refund you the price difference.

Refund Terms & Conditions

The following conditions apply to all lowest price guarantee refund requests:

  • The lowest price guarantee is available to any customer who makes a qualifying purchase through our website. The qualifying purchase must be a minimum of US$20 (or equivalent).
  • The lowest price guarantee covers retail and prepaid rates available to the general public. This does not include discounts or promotions you may receive (or be eligible for) from third-party sites or organizations such as AAA or AARP or special offers made as part of a membership program, corporate discount, daily deal, group, or rewards program.
  • Cool Hawaii promotions cannot be combined with the lowest price guarantee.
  • If you find a lower retail or prepaid rate for the same activity, offered on the same date, time and priced in the same currency as your original purchase, on any other website between the time you book on Cool Hawaii and 48 hours before your trip starts, we will refund the difference.
  • The lowest price guarantee does not apply where a lower overall price is found by breaking down the purchased activity into one or more parts sold separately.
  • Cool Hawaii reserves the right to verify the lower price details. Examples of acceptable forms of verification include a web screenshot or a web address.
  • All refund decisions will be made at the sole discretion of Cool Hawaii.

Sorting, ranking, and search results

Activity name

Cool Hawaii wants to make your searches as relevant as possible. That's why we offer many ways to help you find the right experiences for you.

On some pages, you can select how to sort the results we display and also use filter options to see only those search results that meet your chosen preferences. You'll see explanations of what those sort options mean when you select them.

If you see a Badge of Excellence label, the award is based on average review ratings, share of bookings with a review, and number of bookings through Cool Hawaii over a 12-month period.

The importance of any one factor over any other in a sort order varies, and the balance is constantly being reviewed and adjusted. We're always updating our systems and testing new ways to refine and improve your results to make them as relevant as possible to meet your needs.
