I would say 6 maybe for 2 people. 8 if you are really hungry.
1. Do not, repeat do not go on the week ends friday included. One Sat. we went with my dh insistence. We had also gone a few times during the week After he saw he had to wait in line with 50 people, yes I counted them, just to get a cherry waffle, he listened to the voice of reason, me and we left. This was of course after he had the waffle, lol.
The portions arent all that large. My dh is a big eater. I am not. We could share things but he usually finished them in a couple bites, sigh.
I think most things are 1 snack credit but we never use the dining plan
I didnt do a dining report but I know my favorite is always the lobster roll, the filet from canada, sausage from germany and apple strudel. My dh likes the fishermens pie, anything spicy from africa and most likely anything else. There really are alot of choices, so I would look at the listings which they do publish ahead of time and make a game plan.
You could probably do like 4-5 foods and 3 desserts. If that is your only day/time to go to F and W then that would probably cover a lunch and dessert.
