On your next trip to the Caribbean, pack your best whites: croquet is back. At Turks and Caicos' Somerset on Grace Bay (649/946-5900;; doubles from $285), the 82-foot grass course, opening in October, will have a pro staff to coach neophytes. Modern-day golf rules replace old-school etiquette at Jamaica's Half Moon resort (866/648-6951;; doubles from $275). And on Antigua, Jumby Bay (888/767-3966;; doubles from $750) is hosting weekly tournaments on—surprise!—an AstroTurf lawn.

The Somerset on Grace Bay

Jumby Bay, A Rosewood Resort

The recently redone Jumby Bay, A Rosewood Resort, situated on a private 300-acre island 10 minutes by boat from Antigua, is still the standard-bearer of Caribbean luxury. Following a $28 million reconstruction, 28 new suites have ocean views and outdoor bathtubs in lush private courtyards. But the most exciting addition is the property’s first-ever spa, Sense, an open-air facility with a garden just 50 feet from the beach; book the Sense Hammock Massage treatment for two.

Half Moon, a RockResort

Legendary 59-year-old estate on 400 acres, 15 minutes from the airport, that offers polished service and a multitude of amenities, including a new 68,000-square-foot spa.
