Drink or dessert substitutions allowed for CS on DDP?

[lovetogowdw]

It has been a couple of trips since we used the DDP and even the last time we did use it, I found the substitution rules differed between locations. Can someone tell me if the resorts (especially AofA and Pop) are currently allowing substitutions for the drink and/or dessert on the DDP when using a CS credit? Specifically, can you get milk or juice for the drink and can you get grapes or yogurt (the little cups of yogurt) for dessert? What about in the parks? If anyone has found particular park CS restaurants that allow such substitutions, please share!
