We chose this over kayaking the bioluminescent bay as my wife does not swim. We booked on line at their website two weeks prior to our trip and got the last spots available on the English speaking tour (max 20). We picked our night by checking the phases of the moon and picking the darkest night. An English and Spanish tour were running at the same time. The English tour was full but there were openings in the Spanish tour. The tour lasted 2 hours and included a visit to the lighthouse, were a PowerPoint presentation on bioluminescence and light pollution was shown. We then walked the boardwalk and played in the water to see it light up. Our final stop was the dry forest and beach. Our guide caught and released several small animals and insects that he showed us. My 16 year old son thought the tour was OK (a rave review from a teenager) while my wife and I enjoyed it a great deal.
