W Retreat & Spa - Vieques Island, Puerto Rico
What's free: The only thing better than sipping cocktails while watching the sunset over the Atlantic is when said cocktails are free. Which is every evening at the W Vieques Island's “Sunset Sip", where guests relax by the outdoor fire-pit and knock back gratis island-inspired libations like Puerto Rican rum punch and mango/ passionfruit mojitos.
While you're there: Don't let lame marketing campaigns get to you: WET = the beautiful infinity pool; FIT = the state-of-the-art gym, complete with tennis courts and diving facilities; and AWAY = the resort's ocean-facing spa.
