I wonder if there would be an issue splitting the cost between several people if there was more than one DDE card being used?? Say, for instance, there are 4 people in the group, 2 have DDE, would they give the discount only to those that have the cards or to everyone in the group? THat would seem to be a difficult thing to do...2 with the discount, 2 without. On the other hand, it would be nice if I could have the bill split when I go with another mom and her dd. I have the dde card and I know that other mom is going to want to pay her own way, rather than split costs at the end of the trip. Sure would be nice if they could apply the discount and then split the bill for us.
