This excursion was an amazing- great food and friendly knowledgeable and accommodating captains and crew. The Captains and crew went above and beyond to make trip excellent in the face of uncooperative weather (windy) finding a great spot for us to snorkel and pointing out all the different types of fish. The winds died down just enough to allow them to put out the awesome slide which was a huge hit with my 9 year old daughter. Can’t recommend this enough.
