Unfortunately I have experienced this in all its glory. It's not just you and it doesn't seem isolated.
Two years ago, I believe I posted something on this. It bugs me now just like it did then. When we were there two years ago, my hubby's company had their national sales mtg at BC, and we stayed there with him. Our last night there, which happened to be the last wkd of F&W, the drunks-corporate and college aged-were out in full force. It was my first experience seeing it, and I was extremely unhappy. So much so that I have purposefully avoided F&W or Epcot on weekends at that time. In fact, we are going in November and it ends the weekend we arrive. I have planned our day for Epcot after its over. Kind of sad, and it should be handled by Disney. WDW is a place for families, not a bunch of lushes who can't control themselves.
I would have to say I think with about 99% certainty, Walt would not be happy with it. I have no issue with people responsibly having a nice cold drink. I had a lovely Peach Bellini during the F&G in May. But there should be CM training in place and it should be known that Disney does not put up with overindulging. Until they let it be known it will continue. If that's what they want to attract, then I have no words.
