It’s the ultimate holiday fantasy, ticking so many “take me there” boxes that it’s almost a cliché – the azure Indian Ocean, white sand between your toes, warm sunshine, swaying palms, five-star service… This private-island resort is the sort of place you dream about when city life’s at its greyest. If you can drag yourself away from your hammock, there are two tennis courts, a dive centre and a climbing wall. If that all sounds too strenuous, a stroll on one of the 12 beaches followed by a dip in the infinity pool might suffice.
