It’s hard to imagine a beach more perfect: Sand as white and fine as confectioners’ sugar. Water the same transparent turquoise as a Tanqueray gin bottle. Near constant breezes that straddle the line between blissfully warm and blessedly cool.

But apart from these obvious physical qualities, White Bay, the most popular of seven beaches on the 850-acre private-island resort, Guana Island, has another, less obvious but equally attractive asset.

It’s not the swimming platform that bobs seductively in the distance, offering Guana’s maximum of 40 guests a handy floating tanning table.

Neither is it the little white beach bar on its casuarina tree-shaded sands, where Guana Mojitos (made with organic mint and Key limes from the island’s orchard, naturally), are served with pleasing regularity.

Rather, it’s the lightning-fast WI-FI that extends from that bar almost to the beach’s water line, making envy-inducing Instagram posts and boastful Facebook status updates as easy as pressing “Share.”

Because, trust us: When you’re lucky enough to be on Guana Island, you want everyone to know.
