Emma and Casey were the perfect hosts and guides! Once we checked in, they both called us by our names throughout the trip, as if we were old friends. Nice small group, only 18 of us. Got to see two pods of spinner dolphins; some within touching distance of the boat. Awesome snorkeling, most of which was just our group. Friendly, welcoming, informative, attentive, and most of all, fun! The best excursion of our entire trip to Hawaii!
