The concept of watching these magnificent creatures in their own habitat was very alluring. But, I would urge TripAdvisor to select a different tour operator. The crew was too young and more interested in showing how 'cool' they were than giving their clients a memorable experience. Our boat was the last to arrive and the first to leave the area where the rays were feeding. Many of the lights to attract the rays were broken or malfunctioned compared with what we saw in other boats/tours at the same location. The experience lasted 20 minutes and we saw very few rays. Go see this amazing sight, but select a different tour than Hang Loose Boat Tours.
