We stayed at ASMu, but I'm sure the offerings are similar (and if not, someone will come along to correct me ). I saw boxed doughnuts, cereal, crackers, maybe Nutrigrain-type bars (not positive on that one). They also had full-size bags of chips, and loaves of bread. It was all a lot more expensive than the regular grocery store, but cheaper than buying it in single servings in the food court. There were also a lot of snack-size packs of pretzels, cookies, candy, etc.
Last time we were there-0ct 2013- we saw only the candy , pretzels type snacks. Non of the donuts or larger chip bags or anything like a lot of the other resorts. You had to get items from the food court and the selection was less than prior years.
