I'm a Brit, which as you know, implies that upon entering the world from my Mother I was immediately hooked up to an intravenous supply of pure alcohol. Reading this thread, from that perspective and as a long time regular visitor and lover of WDW has been absolutely fascinating.
As others have said, when we visit the parks, we are on our hard earned holiday vacation, we now always tend to come in October so that we can enjoy the F&W at Epcot. One of the great draws is not just the great food, but the fact that it's like the BEST pub crawl, where you can sample alcoholic beverages from every country. Like most decent people though I would say we would recognisze the correct moment to stop. Being drunk, tipsy, merry (whatever you call it) is a nice feeling, let's be honest and why I drink alcohol, and it enhances the experience.
The reason this debate is so fevered, is that Disneyworld IS a magical place. When I first took my kids there I had the vision you see in all of the marketing, an impossibly cute family in a beautiful empty MK street with joy exuding from every orifice. What I never imagined in that utopian vision was Barney lurking behind the bin with body fluid exuding from every orifice in a tirade of profanity. It detracts from the magic and what our vision of of the day was.
All on this post that have preached tolerance up to the point where enjoyment of others is comprimiszed have it nailed on, and from my experience, that is the the fine balance that Disney is finding well. Please don't deny me my right to enjoy my magical experience my way.
