This felt like a booking trap. We were allowed to book when seats didn't exist and were only informed six hours prior, when it was too late to book with a different vendor.

The tour is an amazing experience and the operators are first class. Our guides were professional, experienced, engaged, and really took care of us. I don't recommend taking the tour in October as the increased rain resulted in a multitude of mosquitos. The guides did their best, but my wife ended up with 80 bites (we counted) so bug repellent is a must in the fall.

What a great experience. Never seen anything like this and would say it’s definitely one of the wonders of the world. The staff were outstanding and not only did they answer everyone’s questions but made the trip extremely fun. Thanks!

We were very disappointed. If you think you might see what is depicted even a little bit while on the excursion... You will be very disappointed. Plus, they don't tell you that the whole area is infested with mosquitoes. This is the biggest waste of money. Look at the photos instead of spending over $150 and getting bombarded with mosquito bites.

Sugar Sugar Bear and his crew were very helpful and funny. They really made the evening enjoyable! Really enjoyed the experience! Take bug spray. We got eaten alive at starfish point, but it was really cool seeing the starfish. As for the bioluminescence, make sure you go on a new moon to really see the bioluminecence at its best.
