"Kate is staying in an incredible villa overlooking the sea," says a mole. "It has two butlers, two chefs, a housekeeper, a chauffeur, a live-in masseuse, and a yoga teacher. But now, Kate wants to have her own place. She thinks it's a good idea to spend money investing in a property for next time and is encouraging Sadie to invest too."
Kate has taken her daughter Lila Grace, nine, on the half-term trip but has left husband Jamie Hince behind. "Sadie's daughter Iris, who is 10, and Lila Grace are the best of friends. It will be a very girlie adventure for half-term," adds the source. "If Kate buys a place with Sadie, it would be the ultimate party palace." Kate has previously stayed at the exclusive Jakes Hotel on Treasure Beach on the north side of the island.
