We're going in July so I don't have first hand experience, but some people have reported being told at CS places by the CMs that they cannot order more adult meals than are on their KTTW card (which specifies how many kids and how many adults there are). But, the credits are (right now anyway) pooled together, so you could solve this dilemma by splitting up to order, with one adult ordering two adult meals and another adult ordering two adult meals, for instance.
That's what we'll be doing when eating at CS places that have really lousy choices for the kids (as many of them do).
