I am at the WL right now. We were able to get the oatmeal at RF which goes for 2.49 as a snack credit, but if you add fruit to your oatmeal, it ordinarily costs 3.99, and you can not use that as a credit. I was told that you have to use a counter service and get 2 drinks with it.
Also, we were not able to get the bunch of mickey head lollypops as a snack. It is 3.99 and last year I was able to do it as a snack, and the CM said that she noticed that alot of items you were able to get last year you now cannot.
We were able to get a strawberry shortcake from Sunshine Seasons in the land as a snack, and that was 3.99.
I am going to Epcot today, and have lots of snack credits so I am going to try to get a few different things and post back.
