Bay, at mouth of the Potomac, is Smith Point Marina. The Bay Motel is newly renovated and close by. Off the Great Wicomico is Buzzard's Point Marina and Jenning's Boatyard. Again, Bay Motel is nearby both.
Run down some but Port Kinsale Marina on the Yeocomico River off buoy #9 of the Potomac River has Oyster Reef Cottage for rent. Pool nice this past weekend but the resturant is closed. Boat ramp. If windy can fish the Yeocomico with out having to go out to the main part of the Potomac. Caught 37 white perch fishing the docks of the marina. Info on marina facilities has not been updated for a few years. Marina web site:
My favorite is the awesome hotel near the causeway bridge on your way to George's Island. You have to call them if you want the best results, but Priceline and Kayak have been helpful. They have long piers and you can fish or dock right there. Tall Timbers has good restaurants, too. It's best to ask the staff for local staff for suggestions.. Hotel restaurant is high quality, but expensive.
