I've had the pleasure of spending the night at Sutton's Bay, and it's a really nice small harbor town. The town earns its living entirely from tourism in the summer months, so they are more than welcoming. If you've never spent a night aboard, this is a great place to start. My only complaint is that the marina is laid out in a straight line extending into the harbor, so the hike from boat to bathroom at 2 am, or to the marina gate to go to town, is long and uphill. Marina etiquette is so basic and laid back as to not need explaining - just follow the golden rule. If you don't want to be annoyed while enjoying your vacation by loud music, noisy neighbors, or drunk & disorderly, then your neighbors-for-the-week probably won't like it either.
