I have mixed feelings on the alcohol thing. I kind of like that it's not served in the MK and DL. But I think I only like it from a traditionalist standpoint. It's just kind of a cool relic from the past. If Walt was around now, I have no doubt he'd sell alcohol in his parks. He had it in Club 66. He had no problem drinking and smoking himself. So I doubt he'd have a problem with guest enjoying it in his parks in moderation once it became more socially acceptable to do so.
At the same time, I don't really care. I like to drink when I'm at Disney, and I have almost never bought a drink inside the parks, outside of WS. If you really want to drink, you'll find a way to do so.
I think a good compromise would be allowing wine and beer at the table service restaurants, but not allow it walking around the parks. I really don't think I want to see people with glow in the dark light cube mixed drinks walking around the Magic Kingdom.
