When my sister and I cruised earlier this year a lot of people had a oval hole punched on their S&S card and a lanyard attached. Will carnival do this when you get your card? Do you need to bring your own lanyard? It looked so much easier to keep up with and not have to worry about having a pocket!
The Purser will also punch a hole in the card for you. I agree; I wouldn't attempt punching the hole myself, the cards to important to mess up. Then I'd have to go get another one made. Carnival sales Lanyards in the gift shop. The kids usually receive a Lanyard from Camp Carnival for their Sail & Sign cards. I like having my card on a Lanyard too.
