Let's say that one day we just don't feel like sitting down for a long lengthy dinner. Can a table service meal be traded in for a counter service one?
There was a sign up at the POP food court when we were there during Free Dining (September 23- Oct 1) that stated TS credits could be exchanged for 2 CS meals and a snack. It was either that or 1 CS and 2 snacks. It was something like that anyway, because you couldn't find a TS anywhere unless you already had an ADR.
Yes, a TS credit can be used for a CS, but why would you want to? You lose quite a bit of value if it is for and adult.
As far as I know, they only offer that during free dining. We used it a lot!
