arrival and departure days.
If you are on the regular basic plan, what we do is use the better credit (TS) on the arrival day and the QS on the departure day. Also, if you have longer arrival and departure days you can use snacks for healthier foods and make a meal of it. In most food courts, snacks can be used for cereal, yogurt, muffins, a small salad, and fruit choices.
We never go OOP with the plan. You can apply the same principles with snacks to enjoy a 2 TS credit restaurant, as well. I can make a meal out of combining snacks and then save a TS credit if I want to try a fancier place for dinner.
Depending on your situation with a car you can stop at a grocery place and get some food that way for the resort room. We carry some items in our luggage like breakfast bars, canned nuts, etc.
We use our credits at Disney very wisely and we usually maximize our return on the dining plan.
I know this is more info then what you asked for, but I think it's useful info.
