I know we have ordered one dinner and split it between the two of us. We have done this with our children, order an adult meal and split it. Cosmic rays which is a counter service in the magic kingdom has a wonderful menue, my husband and I have split the chicken and rib meal and have also shared many meals there. we share drinks by bringing our own cups with us in our backpacks and we have never been questioned. i know many folks bring food into the parks and do their own picnic. If you are going to eat at disney, this is the way to go. I do know that at a buffet such as crystal palace you are all charged and hollywood and vine. Those are your typical schmorgasbord places where you go up and help yourself, those you cant buy one mean and share it. But as I have mentioned at cosmic rays and the counter services, we have done that. I even order off the childrens menue when I am not that hungry. Have a wonderful trip!
