@gouf78,
At the schools I know of that require the full meal plan the cost is rolled into the cost of attendance assumed for FA. A kid on full FA will have coverage for the full price of 3 squares 7 days a week. My kids’ school calls it the “comprehensive fee” and it allows for unlimited visits. The result is an equalizing effect-no “haves” with the full meal plan or spending a lot of money on “food bucks” fast food and “have nots” eating ramen 4 times a week.
I’m sure there are others schools that I don’t know that don’t do it this way but I like this arrangement.
