Unusually, I didn’t leave the British Isles until I was 35, when I went to the Maldives for a fortnight. (You bet it was a culture shock, considering that the most exotic place I’d been until then was the Bognor Regis branch of Butlins.) But I’ve globetrotted like a footloose fiend since then, and on my travels I’ve observed that the pricier the watering hole, the less likely vacationers are to look happy.
