I totally reccommend you reading the link from the unofficial guide...

and they even include the sheets to help you keep track of the menus (some rest/character bkfst/signature rest. charges 2 meals. I love the fact that if you are 'educated' that you could figure out how to 'bank meals' share meals, ie at LeCellier DH and I split a meal, so now it cost 2 'credits' (I like thinking of the MYW as credits as opposed to 'meals') to eat 1 meal at LeCellier, but for us, we ate lunch, told them we'd split, they brought a plate, and it was more than enough food (appetizer, dessert, meal) for both of us!!
