    5/5

    From the first phone call I made to Emmy to coming back to the dock after our 4-hour excursion, everything was absolutely wonderful! My party of 4 booked a snorkeling and sandbar excursion with Seahorse. Our captain, David, and his first mate Mercedes, were awesome. They both know the history of the area and made us completely at ease while on our tour. The pricing was more than fair, and I would highly recommend this company.
