Incredible!

5.00Incredible excursion. Everything from the sunset cruise out to see the starfish (and jellyfish and random manta ray) to the bioluminescent bay was perfect! Guides were friendly, the evening was carefully documented by the photographer, but yes, it was $50nto buy the irresistible photos and videos. It was a pricey tour for a family of 5, but honestly worth it. So unique and memorable. They also had cold drinks and wetsuits for our comfort. The boat was fantastic too.
Fun

5.00Great experience. Mosquitos were crazy! But crew had bug spray so that helped a lot. Other than that it was so cool to swim in the dark and see everything light up like that.
They were excellent! ...
