Yes you can. I had two extra CS left on the last day of my trip this past May. I ran to DTD to use one to get a sandwich from Earl of Sandwich to take to the airport with me and to go by Goofy's Candy store to use four extra snack credits I had. While I was down there, I ran into Wolfgang Puck's for breakfast. I got their cornflake french toast with fresh fruit and a bottle of grapefruit juice. I was very good and would have cost $11.13, if I had paid OOP for it.
FYI: It was three pieces of what appeared to be a sliced bagel, breaded with corn flakes, deep fried, then rolled in cinnamon sugar and had syrup and fresh fruit on top. The fresh fruit were blueberries, bananas, and strawberries. It was very good, by the way.
