So we are going with a party of 18 in 3 different rooms. Our room will have the dining plan and I also have TIW. Since we are on the plan I assume we will have a separate check. Since we will all be together for dinner will I still be able to use my TIW for the rest of the party who won't be on the dining plan. My wife has the additional card so we can cover the whole party. Any experience greatly appreciated.
