Feedback on Seahorse Land & Water Taxi or Great Exploration Tours

[EeyoreRN]

We will be in Crown Bay in the end of May and are looking for a leisurely day excursion to St. John (not a half-day rushed one). Ship is in port 8am-6pm so we don't have to rush. Would most appreciate stops at multiple beaches with snorkeling but would also enjoy a few historical sites and maybe a short hike and a gorgeous vista or two (not necessary, water activies #1 priority). In my search these two tour companies came up and they seem to offer something like what we are seeking. Does anyone on this board have experience with either of these companies? Can you recommend a different idea? We don't want to break the bank $100 pp ideal, would go up to $150ish for something really special.
