Looking for recommendations for a snorkel boat tour in key largo. Prefer one with just snorkelers rather than snorkel and dive. I’ve done the one through pennekamp so looking for one of the private companies. Have done the Christ statue so more interested in a good reef. Seems like lots of choices so was hoping to get recs here. Also- any difference in length of time to get out to the reef between the different vendors depending on where they dock?
