Ok... as promised LIVE FROM POP CENTURY.
I haven't had time to read through the posts, so if I tell you something someone else already has - sorry!
Now, this is our first time on the dining plan, so to me, there are tons of snack options. Doesn't look like your grocery items, large boxes of donuts,etc.. are included - but honestly I never would have expected them to be if I hadn't read it here before. To me, a snack is a SNACK....not breakfast for 3 days.
All the desserts, chips,etc... are snack credits. We had choc layer cake last night as a snack credit.
From what I can tell in the parks, the snack items seem to be pretty much the same as what people reported before, but I haven't looked closely.
I will write more on the actual dining plan in another post.
