I've been by it many times and went in to look around once but never stayed in it. It has, as Flametamr said, that worn look and the sites are close together. Another thing is during different periods of the year there are some folks who set up for several months (gas rig workers, snow birds, summer breakers) giving it that "lived in" look.
On the other hand, it is a short walk through the woods to the beach, the bird sanctuary is adjacent, the ferry across the street, Fort Gaines (civil war era) a block away, and the Estuarium (learning center/museum of Mobile Bay) offers an educational slant. If you have a travel trailer I would say stay there (I have a pop-up and because of the close sites=noise and tired facilities I haven't stayed). It's not convenient to the interstate if you are on your way to the Fort and maybe 1-2 restaurants on the island but if that's what you're looking for this is it.
