If I could give this company six stars, I would. My wife and I booked a four hour excursion, and if you have any doubts about whether that’s worth it over the one hour grotto trip, it absolutely is. We had a fantastic experience, the crew was completely accommodating to our one-year-old, who accompanied us, the chance to stop and swim was amazing -- even in December — and the boat was stable, felt comfortable and was well-maintained.

The food is catered, rather than being prepared on board, but their choice of caterer was a good one, and we took that recommendation to stop at the restaurant later where the food came from.

The four hour excursion includes a trip in a small boat through the grottos, and the crew on that small boat were experienced, playful, friendly, and made the trip very much worthwhile

Our trip was delayed a few times because of weather and a lack of fellow travelers, but that’s to be expected in December, and our schedule was flexible enough to accommodate it. All in all, I’d highly recommend this company.
