We had Ula and Nahlu for our crew and we had an amazing night with the mantas. We took the 6:30PM tour and got to see the sunset as we were heading out of the harbor. We saw nearly 20 mantas that evening and as other reviews state it was an amazing experience.
We choose Hang Loose over other tour providers based on other Tripadvisor reviews that said they were good with kids, provided additional flotation aids (the yellow inflatable vests), and were good with guests with little previous snorkel experience. We were not disappointed and found off these things to be true.
We will definitely use Hang Loose again on future Hawaii trips.
