To the uninitiated, the words "Cayman Islands" have a strong tendency to evoke John Grishamesque images of high finance, secret deals, well-heeled businessmen in sunglasses with combination-lock briefcases conducting their affairs behind the closed doors of the island's 550-plus famously private banks. But unless you happen to be one of the businessmen in question, it's far more likely that you'll come away with another image entirely upon visiting these shores - of blazing white-powder sand beaches stretching mile after mile along the coastline, and of the brilliant multicolored coral reefs lying just underneath the waterline.
