I passed through White's Ferry and Leesburg biking Pittsburgh to DC last July. Leesburg is bigger and busier than the other towns on/near the C&O. The auto traffic is heavier and faster. If it were me, I'd look for a way to avoid biking those two miles.
If you stay at a Leesburg motel, they may have a shuttle that can carry you between the ferry stop and the motel.
