Let me first say that we took a sunset tour, titled "BIOLUMINESCENT" according to their website. Well, from our 90 minute tour, not even 5 minutes was spent on Bioluminescent. Perhaps the name should be changed to simply a kayak tour in heavily mosquito-ed areas. When the Bioluminescent did start, we had to quickly get out because the next tour was starting in 30 minutes. Even the picture they show as the main picture of the tour (or the video seen on their website) is completely misleading. We did not see anything anywhere near to that. I understand that wild life can be unpredictable but then you should not market it like that.
I will add that our tour guides were knowledgable, although very confusing. They themselves seemed to be unsure of exactly what to say and do. The sites preparation tips were helpful with regards to bug protection even though they got me anyways.
I would strongly avoid this tour.
