Hands down the sexiest hotel room award goes to Jade Mountain. Built and owned by the architectural pioneer of the open wall concept, each room (or sanctuary, as they are called) leads out to its own limestone stage where nothing separates you from the view overlooking Jalousie Bay and the Pitons. It may be a cliché, but this is truly a room you won't want to leave on your St Lucia honeymoon. Have your butler bring you breakfast and eat in your four-poster bed. Lounge in your private glass-tiled infinity pool where you can see for miles across the jungle canopy. Feel free to skinny dip — the resort's ingenious design means not another soul will spot you two. And if you do decide to emerge from your sanctuary, book a couple's massage at Kai en Ciel Spa or head to sister property Anse Chastanet, where you can use all the amenities.
