Hi Larry,
The
Epcot International Food and Wine Festival is one of my favorite events at Walt Disney World! As the event draws closer, the website will be updated. Park admission to Epcot is required, but you don't have to pay an additional fee for the Festival. There is a charge for any of the food or beverages you would like to try. There are kiosks set up all over World Showcase and the food and beverages are a variety of prices. If you are using one of Disney's Dining Plans, most of the food items use a snack credit.
There are seminars, tastings, and special dining events throughout the Festival. Several of the seminars are free, but some do have a charge. Any of the special dining events will have a cost and these will vary. I don't know if you've ever visited the disneyfoodblog.com but they have great information about previous festivals that might help you as you plan.
I wish I could give you better information about costs, but they change every year and I would hate to give you the wrong information! Please let me know if I can help you with any other questions!
Wishing you a magical vacation,
Amy H
