Virgin Group billionaire Richard Branson owns a 74-acre retreat in the Caribbean called Necker Island, where his luxury resort can accommodate up to 30 people.

When lottery winners get tired of lounging by the pool or beach, they can hang out on Branson's yacht, the Necker Belle, or explore the sea on his submarine, the Necker Nymph.
