5.00Lori was so amazing, she helped us through the whole experience. She is truly awesome. She's also very fun to converse with. Wouldn't do it with any other team than this.
Very good

5.00It was great even for a first timer like me, my wife loved it. Sadly there wasn’t a lot of glow, but they sent an email out explaining that and we still went to our own discretion, it was still a great experience. The guides were great, Daniel, Miguel, Lori and Brian were all helpful and talked about how they love what they do and shared that with others.
Awesome!

3.00Too many boats on the water and too few guides. Made for a crowded and chaotic experience. Guides in attendance were nice, there just weren't enough of them
Good experience

5.00Good experience! It was a shame that we couldn’t see the bioluminescence, only some sparkles. But all the guides were top notch.
Once in a lifetime experience worth it!
