If you bring chocolate, you’ll end up with a mess in your backpack Chocolate is not a good snack to put in your backpack or bag if you’re headed to a Walt Disney World theme park. It will not take long for it to end up a melted mess. This includes snacks such as granola bars that have chocolate chips. If you have a chocolate craving, you can buy it in many of the gift shops. Eat it immediately, you have permission.
