We also used a CS for our whole family at Pinnochios and it was about the only place that gave us trouble. At every other CS location our children (and us adults) had been able to get those big bottles of Nesquick Chocolate Milk. After all, they are cheaper (or the same price) as some of the other drink options. Anyway, here, we were told our daughter (10 years old) who is an adult on the plan, couldn't get that milk. The two children could.... but those of us who were adults couldn't. We thought the cashier might have been in a snit that day, but it was too crowded to argue or have a discussion. So we had to explain to our daughter that she now had to pick something else.... even though she had been getting it other places just fine.
Go figure. (I don't think she would vote for the dining plan again since it is hard for older elementary children to find adult meals they like.)
All of the other places and TS went well and the servers were nice and very helpful. In all of the other CS/TS locations we were told that any drink that is NOT alcoholic is covered. Any drink called a "specialty" drink is not. Personally, we think the plan should cover a few more snack options. That is very limiting.
It was easy to track the plan/credits. The only other problem we had was at the CS place in Mexico where I tried to get three sodas with a snack credit and the manager had to be called in since I was charged for 3 CS credits instead. But he fixed it and was nice about it!
