Newport, Rhode Island
GET THERE: The posh harbor town is about 200 miles north of New York City.
STAY: The year-old Attwater (from $229; theattwater.com), a 12-room nautical-inspired hotel, is within walking distance of restaurants, shops, and the Cliff Walk (cliffwalk.com), a 3.5-mile footpath that borders the shoreline.
CHEAP THRILL: Mansion tours. The city is famous for its 11 historic Downton Abbey–esque estates (newportmansions.org), which used to be summer homes for America’s wealthiest. Tour The Breakers, the grandest of the Vanderbilt family’s former vacation escapes (tickets, $24 each).
