Wealthy tourists are desperate to stay at the plush estate where Duchess Catherine was photographed topless.
The Royal couple were staying at the secluded Chateau d'Autet retreat in the south of France - owned by Princess Margaret's son David Linley - when the intrusive pictures of the Duchess of Cambridge were snapped last month.
But Prince William's relative is refusing to cash in on the scandal.
A friend close to Linley told the MailOnline that he has been inundated with offers from wealthy tourists hoping to stay at the 19th century hunting lodge since the pictures were published in early September.
"Linley has had mad offers coming in," the source said.
"Kate and William value him as a cousin and a friend and his refusals to capitalise on the publicity have been noted by the Royal Household.
"His currency is his silence."
Following the publication of the topless pictures, William and Catherine said they were left "saddened" by the "grotesque" invasion of their privacy, but the Duchess has been determined to uphold her growing public role and scheduled appearances.
French magazine Closer was heavily sanctioned for publishing paparazzi shots of the 30-year-old Royal without her bikini top on.
