Where can you stay on a private island in the Caribbean?

The Caribbean has roughly 20 private islands that take overnight guests, ranging from a $1,800-per-night cottage to a $250,000-per-week whole-island buyout. The most accessible: Petit St. Vincent (Grenadines, 22 cottages, no Wi-Fi by design), Necker Island (BVI, Richard Branson’s, $80K+/night), Guana Island (BVI, 18 rooms, full-island option), Musha Cay (Bahamas, David Copperfield’s, 11 villas), Calivigny Island (Grenadines), and Pumpkin Island (Bahamas Exumas). A yacht charter solves the access problem differently: dropping anchor in the lee of a deserted cay for a day delivers the privacy without the lodging cost. Some private islands welcome yacht visitors for lunch — Cooper Island and Sandy Spit in the BVI are open to charter guests. Hidden anchorages include several private-island stops.
