If you long for a luxury holiday on a private island that will live long in the memory then why not stay in Mustique where Prince William, his wife Kate and their children Prince George, Princess Charlotte and Prince Louis have just spent two weeks.

The Duke and Duchess of Cambridge took their family and Kate's parents Carole and Mike Middleton to the villa Antilles, a new contemporary colonial style villa set in the Endeavour Hills, with a breathtaking outlook to Bequia and St Vincent beyond, The Sun reported.

Prince William and Kate first visited Mustique in 2008 and have returned for their summer holidays subsequently, always celebrating Prince George‘s birthday there.

Mustique is a small private island part of Saint Vincent and the Grenadines, a small group of islands in the West Indies. It has its own police force and is a no-fly zone. Everyone who enters the island has to register.

The villa was built by Prince William's close friend Andrew Dunn in 2016. Dunn's interior design firm Finchatton spared no expense with the luxury décor.

The villa boasts a 60-foot infinity pool, four private staff (a butler, chef, housekeeper, and gardener), four bedrooms, a study and a choice of indoor and outdoor dining options. Three of the bedrooms have indoor and outdoor showers and all have their own bathrooms.

The all-inclusive menu includes signature dishes such as prawn ceviche, grilled lobster and slow-cooked baby back ribs. Menus can be tailored to suit every taste and preference, according to the villa's website.

Prince George, who returned home with his family on Tuesday, enjoyed the bunk beds the most, according to The Sun.

The price of a week's stay in Antilles, Mustique can range from US$23,000–$46,000 depending on the time of year. In addition, all prices are subject to an 11% government tax and a 10% island fee. An additional discretionary staff tip of 5% minimum is recommended.
