The last summer weekend in the Hamptons is always a bittersweet affair. Make it more sweet than bitter at Gurney’s Montauk Resort and Seawater Spa, which claims a quintessential stretch of sand on the eastern edge of Long Island. Guests can unwind next to the resort’s sand-filtered saltwater pool or on its 1,000-foot private beach, where the Beach Club features cabanas, a restaurant, and a bar. Stay in the resort’s new beach cottages for a holiday weekend away—but not too far away—from the Hamptons hubbub. Prices range from $990 to $3,795 per room, per night for Labor Day weekend.
