The snorkeling was great. Capt Brady and Mate Devon were an outstanding crew! We learned a lot about the history, geology, and ecology of the keys--as well as the cutting edge technology of the electric boat SQUID and why it's important for the future. The service was first rate--and although I've snorkeled around the world, what really impressed me was the attention and support they gave to first-time snorkelers so that they would have an amazing experience. For us, this was the highlight of our trip to the Keys. We would definitely do this again!
