Ahhh...why didn't you say so. All you have to do is this. 1) Purchase 25 pretzel ovens (see below).
2) Purchase all the necessary ingredients for making hundreds of pretzels
3) Purchase some cutting boards, rolling pins, etc.
4) Plan your detailed itinerary
5) Anticipate the times you'll like be hungry and
6) Have the resort set up your pretzel making equipment at the anticipated locations. For example, perhaps you'll be near the The Living Seas at 11AM on Tuesday and 11AM is a common snacking time for you. Just mail a pretzel oven, ingredients, and appropriate supplies to EPCOT and have them place the said items at some convenient location near the entrance to the pavilion. Then, all you have to do is find an outlet for the oven, prepare, and cook your pretzels. Voila. Cheap and easy snack.
Of course, if you don't like pretzels this idea could be modified and used for say, gooseberry pie, antipasto, or lemon tarts.
