Leigh,
My family is leaving for Walt Disney World on October 2 as well. If you see me in the parks, make sure to say hi!
So I don't recall the Walt Disney World website ever having a download of the park map for the
Epcot International Food & Wine Festival available. But a number of unofficial fan sites will post hi-resolution scans and photos of the map long before you or I are there. Some of these include the Disney Food Blog, and AllEars.net. In both cases you will also see some interesting reviews of the foods, and some great photos to really get excited about the event.
Also, when you arrive at Epcot that first day, go to the Festival Center to pick up maps and the event Passport. This is a convenient pocket-sized guide to food booths around the event. It is located in the Future World side of Epcot, in what used to be the old Wonders of Life pavilion that is next to the Mission: SPACE pavilion.
Write me back if you have any follow-up questions!
Have a magical (and delicious) vacation!
