So, where do you vacation when you're a multibillionaire? Try crashing at your billionaire friend's place. According to a source close to Lucy Southworth, Google cofounder Larry Page's fiancée has reserved Necker Island, the Caribbean hideaway of Virgin megamogul Richard Branson, for Larry and Lucy's upcoming nuptials. The location is consistent with the visa requirements mentioned in a blog post briefly published on Fortune's website, then erased. The private resort should offer plenty of privacy and security for the camera-shy couple. Past guests include Princess Diana, whose presence there required a 150-meter security perimeter around the entire island.
