Re: Solomons, MD Marina
We just stayed one night at Spring Cove Marina, a bit further up Back Creek. Huge, private, spotless showers, well-kept grounds.
I wasn't there long enough to explore all the amenities, but I believe they have a free shuttle and loaner bikes to take you into town. There are a small bar/restaurant, charcoal grills and a pool on-site. I wouldn't hesitate to go back.
