If you have the bucks, go for Canouan. It's the only place in SVG with a casino AFAIK, and your wife will have lots of opportunites to spend your money while you're submerged. Bequia is pretty cool too, but no casino and definitely much more laid-back than Canouan. When my wife couldn't take the sailboat anymore, we decamped to the Frangipani Hotel for a few days. If the Plantation House is open, that sounds good too. If you have a problem with whaling though, maybe you ought to skip Bequia. They get all riled to go work on their annual quota of four whales whenver the whales pass through the area - when they get one, it's an island holiday.
