I found that it really depends where you are. We were able to get French toast loaf and iced tea using snack credits at the Main St. Bakery. We got rice krispy treats at the AsMo food court. We also got the chips, the ice cream pops, popsicles, frozen bananas, and small popcorns.
We were not able to get Powerade, but our friends who traveled with us were able to at the AsMo foodcourt. They also got the minute maid frozen lemonades on the snack plan.
The best thing to do is just ask...we had to ask often!!
