  • What would my friends on a snorkeling trip and it was very impressive. The staff were amazing very professional very kind very happy. I was expecting it to feel more touristy and it wasn't it was great we had amazing people on the trip and everybody was calm and polite. We were taken to the protected Reef it was absolutely amazing they took us to where it was not crowded and we got to spend over an hour and a half in the water which was fantastic. We had an amazing day it was very impressive I highly recommend this to anybody :-) thank you everyone that does the trips you do an amazing job
  • We stayed here while we explored the Keys. It was beautiful, clean, and convenient! There are boat ramps, excursions, a museum, campground, and so much more! Be prepared though; throughout southern Florida they have an insect that is like a mosquito but it leaves small blisters instead. Just make sure the bug spray is handy. Definitely would recommend!
