the only fast food places onsite are the food courts at the resorts or McDonalds, there's a McDonalds between Blizzard Beach & the All Stars resorts or another in Downtown Disney. You might be better off just at the food courts, the prices will be comparable to McDonalds value meals (I dont believe the McDonalds onsite have the $1 menu & the combo prices are higher than other McDonalds) & it will save you from having to drive around
