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.
