I agree, Marathon, at least for those of us that have surpassed our 60th birthday, is a much better choice. Lots of great restaurants, Tiki bars, protected anchorage inside Boot Key Harbor, and the price is lower than Key West by a wide margin. However, it's still not cheap. In comparison to many locations along the shores of Chesapeake Bay, the cost of mooring and slip rents is much higher at Marathon. And, even in this economy, for some unexplained reason, the cost seems to be increasing.
