This getaway marks Kate’s second vacation this year. She and her family stayed in the Caribbean paradise of Mustique in January.
For William, this vacation means a break from his part-time agriculture course at Cambridge University, which is set to finish in March, PEOPLE has learned.
Palace spokespeople would neither comment on nor confirm this trip.
March 17, the couple are due at the annual St. Patrick’s Day parade with the Irish guards.
