Yes. The whole dining plan is very flexible. We had Snacks, Counter Services and Table Services for breakfast at various times during our holiday. We were staying at Pop last year on the
DDP, and we used snacks and counter services at the hotel. We had:
Snacks: Cereal with milk (the milk is a special mini pot - plenty for one helping of cereal!); box of doughnuts; piece of fruit
Counter Service: Pancakes with syrup and two drinks
Table Service: The catering facilities at Pop do not offer a Table Service option like POR does, so we had to go off sight for them, but we went to several character and non-character buffet breakfasts - Chef Mickeys, Crystal Palace, Breakfastasaurus, Princess Storybook Dining, Cinderella's Royal Table, etc.
For us, we found it more beneficial to use our Table Services for breakfasts, and enjoy the all you can eat buffets, mainly because my sister is fussy when it comes to food and the lunch/dinner menus would never have anything she likes! We would fill up on breakfast and wouldn't need to eat again until 3/4pm!
We are staying at POR this year, and I have been looking into all the food options, and as far as I can make out, I've come to the following conclusions:
Boatwright's is a Table Service restaurant. If you were to have breakfast there, you could pick something of the Entrees/Main Menu, a drink, and usually with a table service you have a dessert, but those are not given at breakfast. I think last year you were able to have a starter instead, but not entirely sure as our breakfast TSs were all buffets and not selective like Boatwright's. This year the DDP has changed slightly (starters are not included) so I'm not sure how that effects the breakfast TSs.
Then for a CS or snack, you'd have to go to Riverside Mill or Sassagoula Floatworks and Food Factory (POFQ). Generally, anything that is $4.99 or less is counted as a snack, anything above that is a CS. Starters/desserts are (unless a signature starter/dessert) are classified as snacks, and anything on the main menu is a CS.
That is based on what we were able to have a Pop. Not having been to POR before, there might be some variations, but I know that the above seemed to be the general rule last year. I'm sure someone who has stayed at POR before can correct me if I have any of that wrong!
