OP, another nice (maybe even nicer) town and rest stop near the trail is Shepherdstown, WV. It's adjacent to the Potomac river, so the detour is minimal. Right after you bike under the road bridge which crosses the Potomac, you turn left to exit the towpath and you go a very short distance (maybe 0.2 mile) up (yes, up) to route 34. Then you turn left onto route 34 and you're quickly across the bridge and practically in the middle of Shepherdstown. The main drag is West German St. Turn left onto West German and there's a good bakery 2 blocks ahead, the Shepherdstown Sweet Shop Bakery.
