Vieques: it’s the beachy island outpost off the coast of Puerto Rico, one that’s still largely off the radar of most Caribbean travelers.

It’s beyond laid back, a place where semi-wild horses roam the streets and a Jeep Wrangler is the preferred mode of transit.

It’s also home to one of the Caribbean’s hippest hotels: the W Retreat & Spa, a sleek, modern getaway with a beautiful cliffside beach, a terrific spa and easy access to the island’s adventures like the famous Bioluminescent Bay and the more than two dozen stretches of sand that dot the edges of the island.

And now it’s even easier to stay there with the property’s new Sunsation Savings package, which offers a complimentary night’s stay, a dining credit and a complimentary room upgrade upon check in.

That means a third night free and a $100 dining credit for travel now through Nov. 2, with a fourth night free and $100 dining credit for stays between Nov. 3 and Dec. 20.
