Hello Rita!
Mmm, snacks. Your coworkers and I speak the same language. I have not seen Disney-themed M&Ms for purchase in the Walt Disney World Resort, but there are plenty of Disney-themed snacks available. For me, anything "mickey-shaped" is not only delicious, but it also puts a smile on my face.
Goofy's Candy Company in Downtown Disney would be my number one stop for treats to take home to win the 'best co-worker' award. You can find a great variety of packaged snacks such as character gummies and cheese crackers in the shape of a Mickey head. They also have classic treats like taffy, circus peanuts, sour cherry balls, and lollipops in Goofy's Candy Company packaging. You can also grab yourself freshly dipped pretzel rods, caramel apples, and marshmallows. You get to select all your toppings!
Another favorite snack spot is the Main Street Confectionary located on Main Street, U.S.A, in Magic Kingdom park. And for convenience, you can also find some packaged Goofy's Candy Company and other treats like cotton candy, mickey-shaped pretzels, flavored popcorn and boxed chocolates in the theme park gift shops and in Disney Resort hotels. Sweet dreams really are made of these.
Happy taste testing!
