She acquired Skorpios Island and its neighboring islet Sparti for a staggering $150 million—making it one of the most expensive island transactions ever recorded. This 74-acre Greek gem holds tremendous historical significance as the site where shipping magnate Aristotle Onassis married Jackie Kennedy.

Lanai holds the distinction of being the largest privately held island in the United States, boasting nearly 50 miles of pristine coastline. The island hosts multiple Four Seasons luxury resorts, allowing visitors to experience the paradise without needing personal connections to its owner—a unique approach among the most expensive islands in the world.
