College Meal Plans - When does it make sense to buy the "Maximum" plan?

When I was in school, the “complete” meal plan was lunch and dinner Mon-Sat and brunch on Sunday, no breakfasts served, so 13 meals a week. I had no money for anything not provided in my meal plan and was hungry (and painfully thin) most of my undergrad years. If we had had to pay for our son’s meals at school, we would have opted for whatever the maximum was just due to my early food insecurity. Anything outside the plan would have been on him. (He ended up at a service academy where the meal plan was all-you-can-eat-in-twenty-minutes 3xday.)
