We were there in May and had no problems with the DDP. The new snacks had just become available, but were clearly labelled as to what counted as a snack credit. I did ask about one thing that wasn't labelled and was told that the label applied to everything in the case.
At most TS, we were clearly told what was on the plan--like smoothies and milkshakes. We found that the menus had been changed in some places (Teppanyaki) to make things quite clear. It didn't seem to be a CM thing whether or not smoothies were a beverage but rather a restaurant policy.
We didn't try anything odd...like paying OOP for kid meals to use credits purchased at child's price to obtain adult food.
