I agree what the heck?? Had no prob finding 18 CS for ME and DW for a 9 day stay. And we were even given another 1 CS ea. @ Columbia Habour House with the Keys to the MK tour and 1 day we were away all day. We get an early start so breakfast is worn of by 11 am so if you head to the CS places then they are not crowded.
If you are not huge eaters (especially in the Florida heat), a full lunch is not always necessary. For myself and my dd (9).. as I said, we share 1 adult CS. We would have usually used more CS credits, but with club level, and all the snacks and appys, we snacked a bit in the lounge. We would usually go back to the resort midday or early evening to use the pool, rest, or just change.
But even when we didn't stay CL, we still have CS credits left as we still usually shared counter service lunch. One of our favorites was the chicken at tusker house. Enough for 2 easily with an extra side of fries for DD.
We always used all of our TS, and usually the snacks too because we'd get donuts or a pastry for breakfast in the room the next morning.
For bigger families, I can see them sharing meals, and since there's a lot of food in the
DDP (until next year

), there's plenty to share without using 1 credit for each person.
