Harbor Hotel, on the far east end of Commercial St, is a throwback to old-school family vacation–style motels. The rooms are quite nice, but you'll likely spend most of your time out back in the pool and cabana bar, or by the massive fire pit in the front. The town center is a 10-minute walk away.
During spring and fall some of the amenities such as the pool or restaurants may be closed or operating under limited hours. Best to confirm before making a reservation.
