Lol the red jacket is the opposite place I’d suggest if you are looking for cozy & quiet down time. Kids up the wazoo.

I’d look at the Notchland Inn in Hart’s Location. From there you can go splurge on spa treatments (Debony Salon in Jackson, or there’s a foot soak place in North Conway). I’m sure Portsmouth would be lovely if you wanted something more walkable for amenities, though!
