Yes there are a lot of choices for a snack as you can see by my thread.
Some great choices to take along (we brought home many of these):
Fudge-available in many locations in the parks as well as resorts and Seashore Sweets on the Boardwalk;
Any of the candy at Karamel Kuche in Epcot;
Chocolate Dipped Mickey Mouse Rice Crisped Treats (at many locations inc. resorts);
Character boxed candies (again at many locations);
Glazed almonds or pecans (many locations).
Here are a few of our take home SC from last Oct.
Character boxed candy-BTW these nonpariels were very good.
Glazed nuts-these are the pecans.
Not your run of the meal snacks, to eat-not take home:
Pretzels-Cream Cheese, Jalapeno, Mickey Shaped;
Pesto Bread at new AoA food court;
Freshly made potato Chips at Friar 's Nook;
Soups (many locations);
Onion Rings (Pecos Bills, Cookes of Dublin);
Funnel Cake (except in Epcot);
Dole Whip;
Ice cream sundae or Ice Cream Cookie Sandwich (many locations);
Iced Coffees;
Pastries (Sunshine Seasons, French Bakery);
and so much more.....
