The largest island in the contiguous United States reaches a long arm out into the Atlantic from Brooklyn to Montauk, where the King & Grove hotel group has followed the summer crowds east. Set in a patch of lakeside woodland, Ruschmeyer's resembles a retro summer camp, with ping-pong tables in the beachy Blackwell Rum Shack, activities from bike-riding to bingo, and live music performances. The restaurant serves fresh Montauk seafood, while DJs entertain in the Electric Eel Disco.
Ruschmeyer's, 161 Second House Road, Montauk (001 631 668 2877; kingandgrove.com). Doubles start at $275 (£183), B&B.
