OK i'm going to try and have my kids share some meals but if they do, can you purchase an extra child size drink? how much is it since most meals come with drinks and seem to cost an avg of just $6.00 for food and drink.
Counter service should be no problem - check the AllEars website for updated menus of all the WDW restaurants. At table service, I think you can do it, but I'd doubt it would work at a character breakfast. Definitely will not work at a buffet!
