Are the DDP credits on one card or on all cards?

[Ahnberg4]

Do you have to give the server each room card every time you eat, or are the credits on only one card? We leave in a couple weeks and that is one of the few question that I haven't asked the DIS yet!!

You just have to show one card per room at a meal. All cards have the credits though so if all members in one room do not eat together each person could use their card wherever they eat and be fine. All the cards are linked to the grand total of credits.
