Great adventure - The guide was so knowledgeable and great with our family.... he was aware about dangers of jellyfish and properly advised all. The lagoon was magical and the adventure was one for a lifetime.

Spectacular experience!! - Spectacular!! The crew was so nice and professional. They made sure we felt safe snorkeling in the bioluminescence water at night. They videotaped us swimming in it which was amazing. Definitely one of the best tours we have been on!

Jellyfish beware - The trip was just okay. They don’t tell you about the jellyfish until they get you to starfish point. This ruined the adventure

Underwhelming - The captain and crew were great however the experience was underwhelming. We saw nothing remotely close to pictures featured in advertising. Save your money and do something else.

Not worth it - We never got to go. We received a text to watch our email for additional information. We continued to watch our email but received no additional email. The only email we received was from Trip Advisor stating that the pickup time was 6:30 pm in front of our hotel. Turns out they changed the pick up time & didn't tell us. We missed the entire experience. This is expensive too. I would never book this again and I certainly won't book anything via Trip Advisor again.

No show and unreachable - They never showed to pick us up and were unreachable by us, the hotel or Viator. Company does not seem to be well known locally.
