Very cool experience! - This was a very cool experience. Getting in and swimming and seeing the waters light up glowing blue made it amazing. The guides were very informative about the starfish and jelly fish as well. The whole experience was awesome.

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!

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.
