Take a peek at Larry Ellison's swanky Hawaiian island suite that costs $21,000 a night

When Larry Ellison bought most of the island of Lanai in 2012, he obtained two Four Seasons hotels. The Oracle founder spent years renovating one of the properties and in February the spectacular new Four Seasons Resort Lanai re-opened.

The new resort offers the kind of luxury you'd expect from a self-made billionaire with an obsession for high-end real estate.

Ellison was heavily involved in the design details and reconstruction and had the designer Todd Avery Lenahan and hundreds of workers "redo the lobby from scratch four different times, until the ocean views on entering were framed just right," reports Bloomberg's Charles Runnette.

The renovation also including adding a $21,000 a night suite (among the most expensive in Hawaii) called the Ali'i Suite.

Ali'i is 3,984 square feet with three bathrooms that can accommodate 6 adults and two children. Naturally, it features spectacular ocean views.
