Just remember that the CRT is 2 TS credits for each diner. But, also remember that you can use as many TS credits per day as you want, until you run out! (Then you'd have to eat all CS and snacks the rest of your stay, or pay out-of-pocket (oop) for any other TS meals.) It's not limited to 1 TS, 1 CS and 1 snack per day - they are all available until they are gone.
If you look on the DDP FAQ thread, there is a link to the 2007 brochure, in Adobe reader form, that tells you what meals are "signature" and require 2 TS credits.
Last year we did a character meal for every table service. Just keep track of how many credits that meal uses. You will get a receipt with what you have left after each meal.
