TROPHY: The property developer bought a 140-acre private island in Fiji in 2011 and spent millions fixing it up. Renamed Kokomo, the pseudonym of a composer whose music he played as a child and the name of all but one boat Walker has ever owned, the island opened to visitors in March 2017. The luxury resort is enclosed by the Great Astrolabe Reef, and is accessible to travelers only via private seaplane or helicopter. Guests can book the whole island for $130,000 per night.
