that's a link that describes the
ddp for you. all of your credits get pooled, so for the time you are there, you will have 7 nights worth of credits per person. that means 7 counter service, 7 table service, and 7 snacks multiplied by the total number of people. you can use them any way you would like. some days 2 table service, some days 2 counter service, or use 2 table service at once for a signature meal.
each counter service includes - either a complete Combo Meal or one entree with one dessert (Lunch or Dinner) or one juice (Breakfast)
each table service includes - entrée, dessert or full buffet and non-alcoholic beverage
plus snacks, which i think disney has pretty much included most single serving items under $4
so if you choose to eat breakfast @ pop, you'll get a meal, plus a juice, for 1cs. if you will be eating cs for lunch, and think it would be a better deal to use your cs for lunch, then you could pay out of pocket for whatever breakfast items you choose. it's up to you. flexible.
sorry if that was long and confusing. any more questions, feel free to ask!
