Necker Island: Like many islands, Necker Island is privately owned by a famous billionaire: Sir Richard Branson (owner of Virgin Records). Accessible only by helicopter, this British Virgin Island is said to have a luxurious villa large enough to comfortably house 28 of Branson’s guests. Only high profile people like Kate Winslet and the late Princess Diana of Wales have stayed there. Google founder and fellow billionaire Larry Page married his long-time girlfriend on Necker Island.
