DH and I are looking at traveling to New England for a week in August while our kids stay with grandparents (so an adult trip

) First time to this part of the country for us both. Neither of us are lie on the beach people, but have enjoyed traveling in the past to beach areas that aren't too touristy or overbuilt-- like Hilton Head and Monteray. We'd like some low key R & R. I'd be content to spend the afternoon in the shade with a view of the ocean reading. DH would love some hiking and/or biking trail to explore. We'd also love some good food, and a cute town that we can walk around and explore. Maybe one or two nearby day trips. Since we are traveling without kids, we are looking more for a B&B type place or hotel than cottage or cabin. Ideally, we'd like to drive less than 12 hours from DC, but would also consider flying. Budget $1500-2000 for lodging for a week, plus food and entertainment. Ideas?
