Royal mom-to-be Kate is on a winter escape, enjoying the sunshine of a Caribbean vacation.

She and husband William are sunning themselves on the paradise island of Mustique.

They are staying in a luxury $28,000 villa, reports the U.K.’s Sun tabloid.

The island – which was popular with William’s late great aunt, Princess Margaret, and is still hopping today with such celebrities as Mick Jagger – is a regular family vacation destination for the Duchess, whose parents, Carole and Mike, are said to be staying in a villa nearby.

Last year at this time, Kate and William stayed at Mustique’s magnificent (and secluded) Aurora House.

This vacation comes at the same time Kate’s office announced she is getting back into her public engagements.

On Feb. 19 she is due to check in on a facility run by one of her charities, Action on Addiction, which offers “a safe, secure and comfortable place for women to recover from substance dependence and receive additional support for other compulsive disorders.”
