Really, this might sound rude, but the only people who will drink are probably going to be middle aged men who bring their children, those are the only people I saw drinking at Epcot, one woman about my age was a liiittttle bit plastered, but I really don't think anyone will have too much in the Magic Kingdom, honestly, who gets drunk in the Magic kingdom? While I don't believe that drinking is necessary in the disney parks. I don't think anyone needs to worry about rowdyness. Having just turned of the drinking age, I should want alcohol everywhere, so I'm told. Not at Disney though. I thought it was unnecessary at Epcot. But I guess they NOT a cultural experience.
