Remember the later in the season it gets the shorter the days. You need to figure that into your stopping points. I like the alligator river marina as you can fuel and eat and dock there. I heard it just changed hands but I would still make it a stop just to check it out. I don't know where you're starting from in VA but I like the Tidewater Yacht marina. Last time there it was awesome, also fuel, food and dock. Don't know how far south your going but in NC, I really loved the River Dunes Marina in Broad Creek off the Neuse River. I don't take the Dismal Swamp route, just don't see the need. Either way have fun.
