So I am a newbie to cruising but not to traveling. I have both a passport and a passport card to make life simple and because you just never know when you need an extra form of ID. Being female, pockets suck and I do not like to carry purses because they are just too easy to be stolen. So for ports/traveling I carry my passport card. For clothing I wear a skort that has a rear zip pocket in the small of my back that keeps my credit card and my passport card. It's virtually impossible to pickpocket because a, noone knows its there and b. you have to lift my top, unzip the pocket and unwedge the cards out. Call me paranoid but it works for me. EFHUTTON/AmericanExpress Never travel without it. lol But if I'm in a pinch I have ID and money.
