We are considering renting a home in the FL Keys on canal/waterfront and taking our boat (21 SPX). It looks like there are plenty of things to do and see. Anyone have any experience in the area or doing similar? Looks like my wife has found a few houses on Marathon. We would probably be most interested in cruising to some sandbars, beaches, sightseeing and some reef snorkeling. Cost of renting a boat for a day appears to be more than what it would cost me to drag my boat down and back from SC.
