Was just there last week and used 5 snack credits for our trip home. Can't get everything in the store, but can still get some good stuff. We did the make your own snacks - pretzel rods, rice crispy treats, and cookies.
Yes, it is. I just got 3 pretzel rods dripped in dark chocolate, embellished with Pecans, crushed Butterfinders, and milk/white chocolate chips (1 embellishment per rod) and then drizzeled with milk chocolate, all 3 for 1 snack credit!!!!! I was told than anything that is a single serving and is under $4 qualifies for a snack credit at Goofy's.
They are definitely on it... or frustration is that nothing in the store is marked as snacks, so you have to ask. I tried to get someone to give us a list of what was considered snacks so that were could select the right things, and no one had a list. I was told "pretty much any single-serve item under $4", but then they pointed to items that met that criteria and were not snacks.
We ended up leaving and going to a store where the snacks were marked.
