caroline - you asked what was included for a CS breakfast. Here is a sample of what I got at Pop Century's food court for breakfast:
Four chocolate chip pancakes (AKA: the Chocolate Chip Pancake Platter)
One sausage patty
Three strips of bacon (on some days they put two strips on the platter though)
One pint of strawberry milk
16 oz. Orange Juice
In other words, a platter breakfast (some days we had waffles with meat other days pancakes with meat, or one day a waffle with fruit topping and whipped cream but no meat with that one), and 2 drinks. Since we had refillable mugs, we always got a milk and a juice along with the CS, we just got coffee in our refillables and not as a beverage with the CS. This one breakfast was shared among 3 "not big breakfast eating" adults. We also had some breakfast bars we had brought along to supplement if need be.
We hadn't planned on using CS for breakfast, but we found we were often sharing 2 CS among 3 adults for lunch on many days, so were starting to accumulate CS credits and started using one here and there for breakfast.
Hope this helps answer your question. This was in Sept. 2007, it was warm, so the heat took down our appetites somewhat.
I hope you enjoy your trip! Planning is half the fun too!
