What better way to bond with your partner (or close friends!) before the baby arrives than to book a stay at an adults-only resort? (It'll be a while before you can visit one of these again, after all.) Consider Ladera Resort in St. Lucia. Nestled on the ridge of a volcano above the Caribbean Sea, the open-air rooms offer total privacy from other people while letting you get completely immersed in nature. This is the only resort in St. Lucia that is situated on a UNESCO World Heritage site and offers breath-taking views of the Pitons and the ocean.
