Basically I think about anything under $4 will be a snack at a resort food court. It does get confusing, when we stayed at CBR for our first DDP trip, I just asked the cm cashier to make sure. Its pretty easy in the foodcourts to determine. Its when you get into the parks, it gets more difficult. Especially at Epcot where many under $4 items don't qualify as snacks. France in particular comes to mind. When in doubt, ask before you buy! The DDP is really easy to use for the most part and after a day or two becomes second nature. Have a fun trip!
