I have to agree with the above poster. We were there May 2007, so the old plan, but the CS didn't change. Even at the SAME CS location (Cosmic Ray's), we got different things each time!! On our very first day, we got a chicken nuggets meal, applesauce, grapes, drink and a dessert (same as adults - we got the chocolate cake). This was great, as our DD was only 2, so she shared with her brother. On our very last day, DS and I went there again. This time, it was a choice of either 2 sides OR 1 side, 1 dessert - and the dessert available was only a pudding cup, not the adult desserts. Not a big deal at all, but an inconsistency.
It really varied everywhere else - some places it was 2 sides + dessert. Some places the choice as above. Some places 2 sides only, no dessert option offered.
I'm a planner, too, so I like to know in advance, but it didn't end up being too big a deal. With 4 kids though....I guess I'd just ask them in advance, if they can get dessert, what to they want? But no promises, LOL
