There were a lot of great snacks available in 2009. We just did the deluxe plan for a week, from 1/2/09 - 1/9/09. Snacks I got include:
-churro
-dole whip float
-mickey ice cream bars
-nuts
-"nachos" (not that good)
-pastries at Norway in Epcot
-fruit cup at hotel food court
-pastries at hotel food court
-smoothies at Magic Kingdom
-fudge at Main Street Confectionary
-chocolate dipped marshmellows at Main St. Confectionary
-rice krispie treats
Things I didn't get but had snack credit icons:
-ice cream in many places in all parks, both at carts and walk up counters, everything under $4 seemed to be included, like sundaes, cones, etc.
-crepe stand in Epcot France
-large soft pretzels throughout the parks
-desserts at counter service restaurants under $4.00
-most side dishes at counter service places under $4.00
-large selection of things at hotel food court (All Star Music had a big sign of what was available as a snack)
There were some carts in Epcot and AK that didn't take the plan at all, mostly the fancy coffee and tea stands. It looked to me that possible the patisserie in France wasn't taking the plan, but I couldn't even get in to see the sign well. I don't think I saw the icon next to any of the items, but I can't really confirm that one.
