We are using the DDP on our upcoming trip, but I am a little concerned about how DD9 will do with this. She is not a big eater, so childs portions are fine, plus we are doing a lot of buffet and family style dinners where she can pick and chose. My concern with with CS meals. She can only eat so much mac and cheese (she is not a big meat eater) so I am wondering if you are ever allowed to pay the difference for a CS adult meal. For example, on one menu I saw that the kids meal was $5.99 but her favorie vegie burger is $1 more on the adult list. Could I pay the difference and let her get the veggie burger?
