I find it easiest to take a sheet of paper (or excel spreadsheet if you're into that sort of thing) and draw a row of seven squares on it.
Get on the dining page on this site, or on allears.net, or someplace and look through menus. Decide whether you want to spend each night's TS credit on breakfast, lunch, or dinner, and which ones you want to try.
Write one in each square, keeping in mind that one of your squares will have to be left blank since a 7-day-six-night stay will only have 6 nights of credits.
If your trip is April or sooner, you can get on the disney site and gather up the park hours for each of your days, kind of figure out where you want to spend each day. This can help you decide which 'square' belongs to which day.
Then make a list of your squares, with dates and time ranges (i.e., April 22 - Crystal Palace - 1:30pm to 2pm) and send that to your
Travel Agent who, if she is worth her stuff, is going to handle the actual booking for you and return to you a list of your confirmation numbers.
