My wife and I are doing this in October. The F&W festival REALLY puts a crimp in the plan though, selection overkill!
I would add that for wine lovers, the wine store in Italy does tastings for a fairly reasonable (for Disney) price. The girls working there are pretty knowledgeable as well. BEWARE that you are very likely to walk out with an expensive bottle of wine, and one that your alcohol dulled palate (and brain

might have selected that your later sober one would not.
For the chillier months, Germany has a kiosk selling Glühwein, which is a sweet spiced red wine served warm (well, hot when they give it to you). Lots of sugar and insanely overpriced at $5 (a BOTTLE usually costs about what they charge for a cup!) but can hit the spot if it is brisk.
I've never seen anyone just falling down drunk at Epcot, but I'm sure it happens. Next time I go I'm REALLY gonna try to explore each pavillion in depth. Thanks for the tip about the tequila bar in Mexico. I usually skip that one, this will change that.
Now just to figure out how to time Morrocco for when the belly dancer is performing. "Why honey, what an AMAZING coincidence!"
