Probably the most famous case like this involved the eccentric billionaire Howard Hughes.
The story starts in Las Vegas and the Hotel Desert Inn which, at the time, was owned by Dalitz.
At the time, the Desert Inn hosted the largest casino on the strip in Vegas. Hughes moved into and rented the top two floors of the hotel on Thanksgiving Day 1966.
After a couple weeks the hotel owners wanted to get Hughes to leave as they felt his eccentricity was negative PR for the Vegas image of their hotel. They also wanted to make room for the high rollers expected over the upcoming holiday season. Hughes was also perceived as a little crazy by this time in his life.
Instead of moving out though, Hughes entered negotiations to buy the Desert Inn. He managed to purchase the resort from Dalitz for $6.2 million in cash and $7 million in loans.
Hughes lived, worked and never left his 250 sq. ft. bedroom in the hotel. The windows and doors were taped shut. No housekeeping was allowed in. He conducted a large amount of business from the phones of this small, darkened room.
He was finally carried out four years later on a gurney and flown to the Bahamas to live out the last few years of his weird life.
