Far from it.
At Pinocchio Village Haus you can easily get a meal based on snack credits. You can get Tomato Basil soup, Caesar salad, breadsticks and french fries, all on a snack credit. Tomato soup paired with salad or breadsticks, or salad and breadsticks, makes an excellent light lunch.
At Sleepy Hollow Snacks you can get a Mickey Waffle topped with strawberries and whipped cream with a snack credit, which is a filling breakfast for many people.
Liberty Square Market you can get pretzels, fruit, yogurt etc... For a light lunch, a pretzel and side of fruit would be fine.
Columbia Harbor House you can get clam chowder or chilli.
Casey's you can get french fries, chilli-cheese fries, or mac n cheese.
That's just at MK.
