hello - I will be in Disney from 9/23 to 9/27 with friends . None of us have experienced the food & wine festival in Epcot. We don't want to spend extra money on expensive ticketed events ( like gourmet meals) . what can you tell me about the event, costs involved etc. Can we just walk around & "sample" things? Approx how much can we expect to spend walking around sampling a few food items/ beer/wines? thanks!
