www.centerharborinn.com is a good one stop spot w/ motel directly on the water, nice dock, boat docking, trailer parking, large public beach, boat launch close by, decent supermarket, and hardware store w/ boat items, plus a post office & church and a few other stores, kayak rentals, ice cream and bagels and breakfast & steamers all within a short walk. Plus a $150/2 restaurant.....!
Could be a 4-star best bet.
Oh yeah, and it is located in Center Harbor.
