I would HIGHLY recommend using Sea Quest Hawaii! Our family did the night Manta Ray snorkel. This did not disappoint at all! From the moment I booked with Sea Quest, our trip was easy! They sent me confirmation email right away. They also called me a few days before to remind me and see if I had any questions. Their directions on how to get to their location was spot on (including where to park). I also loved that when we got there they were working out of a building (a few other companies were out of vans or just a table). All the equipment we used was clean and you could tell they cleaned, sanitized, and took good care of it. They walked us through everything! The excursion itself was also amazing! I loved seeing the Manta Rays, not to mention our staff (Zach and Liz) were so knowledgeable about the Manta Rays we were seeing! We also got hot chocolate and cookies after. They have a super cute shop that you should check out as well. I would absolutely use Sea Quest in the future!!!!!
