The last time we went in 2009, there was an excel spreadsheet that someone shared with me (and others here on the DIS). You could put in about what each person's meal would cost, after looking at some of the sample menus, and it would calculate your totals. Then at the bottom it compared to the cost of the dining plan and the deluxe dining plan so you could decide what was better to do. Is this spreadsheet still floating around? I'd love to get it again. I'm sure I could do something similar on my own, but it was really nice.
