Good day, we wish that they would include at least one more diet pop with the pop cards as we are dietetic and also doctor orders can not drink any cola product. We are not allow to drink the diet coke. So we never get this card. We always have to bring our own diet pop on board with us. We have written e-mails to the cruise lines and get the normal response that they will look into adding more diet pop to the card, but of course they will not. We know that they can't include every diet pop, but at least put one more that is not a cola drink.
