Here's some homework for you: the American dollar is only worth 80 cents in Grand Caymen, at the exchange rate for the Caymen dollar So everything costs 20 per cent more on that island. Plus, they add a 15 per cent gratuity to all restaurant tabs, so your meal there is now a total of 35 per cent more than, say, St. Thomas. My sister has a timeshare condo there, and I spent a week with them one year and found out how really expensive everything is there. My wife and I took them out to dinner at a nice upscale restaurant, and spent $185 for the meal!! Just taking a cab anywhere can cost a bundle! Needless to say, we stay on ship whenever we hit that island on a cruise.
