Prince William and Kate Middleton have a reputation for being a jet-setting couple of royals, but their ultimate favourite vacation destination is the Caribbean!

According to My London, the pair has a special affection for the Caribbean island of Mustique, which is located south of St Vincent and the Grenadines.

The lovely location is not just a favourite of the Cambridges, but also has long been linked to the Queen’s late sister, Princess Margaret, who had a property on the gorgeous island called ‘Les Jolies Eaux.’

Kate is such a lover of Mustique, according to Vanity Fair’s royal journalist Katie Nicholl: “If she wasn’t with William in Balmoral, the pair was skiing or holidaying on Mustique.” Kate was so frequent at Mustique that the tabloids called her the “Queen of Mustique.”

Princess Margaret held the title at one time!

Even after having children together, the couple continues to frequent Mustique; Prince George was once seen being carried off a plane by Kate on a trip.
