Jade Mountain Resort, St. Lucia: With an innovative design of open fourth walls, private in-room infinity pools, jaw-dropping views and wood canopied beds, the Jade Mountain&#39;s are arguably the most romantic rooms on St. Lucia. The unwavering silence, doting service, organic cuisine and lack of technology (no TVs or radios in rooms), make it the perfect spot for an upscale romantic getaway. And the adults-only policy certainly doesn&#39;t hurt either!
