The Duchess of Cambridge and her young son have joined the Middleton family for their annual holiday at Mustique – an exclusive and private island with only 74 luxury villas and a small hotel.
The Middleton family have previously rented a villa on the island which cost £19,000-a-week.
Kate and George travelled without Prince William, who remains in the UK due to his agricultural course at Cambridge University.
However three Royal bodyguards are said to have accompanied Kate and George on the flight.
The future king is expected to make a much longer journey in April when he joins his parents on their tour of Australia and New Zealand.
