Do you booze when you cruise? Plan your consumption around port stops, to restock?
Or do you calculate whether the soda card is a worthwhile "investment"?
Or (horrors) just survive on Lido Brand iced tea?
Or are you that special life form that drinks the ship's tap water?
Since I discovered I have gout, my days of JD & beer are history.
It's Diet Pepsi Twist now.
(Good luck finding that on a ship, Mr. Cynic... I had a good laugh on my last cruise trying to order a "root beer".... you gotta try it, the blank stares are PRICELESS!!!)
