I honestly don't think Food and Wine really causes greater crowd levels over normal, but I could be wrong (though I won't admit it).
Evening EMH will cause a swelling closer to closing time.
If you are considering Epcot on Tuesday morning, be there at 8 AM for the EMH and hit Future World hard. Try to get as much done before 9:30 as you can. At that point, either grab breakfast and wait for the open of World Showcase, or hop to another park altogether.
