No one has mentioned that on Carnival you can get your card punched. And, they give you a free cord to put it on. I think it is just in the casino not sure. The cord is long and can be clipped to a purse, belt loop and if you want you can clip it together are wear it around your neck. I don't recal if Royal Carribean had it It is nice if you play slots it helps you remember to take it out of the machine.
