I think it's beyond naive to think that having a ban on alcohol in MK decreases or eliminates alcohol issues in the park. MK may be a dry park right now, but all I have to do is head out to one of the resorts on the monorail loop and there you have it- full bars. And it's been this way for years...and anyone who thinks otherwise is just denying the long term reality of how people have handled the cocktail/drink situation with MK for ages.
So let's see...I can walk to the Contemporary in under 10 min, grab a few drinks and then head back to MK once I'm done- and the walk is short enough that it's really no different than walking between points in MK. Sure, I didn't drink those drinks in the park, but the end result is the same ...so there's really no difference.
In fact, it's pretty darn easy to drink your way around the world at Epcot and then catch a monorail to get to MK. So, a little more transportation time, but still the same end result.
As for bringing Walt into it...you're quoting things from a VERY different day and age. On top of that, people are treating this like Bourbon Street is being added to the MK...i.e. grossly blowing this out of proportion. We are talking about beer and wine to enhance the food offered at a new restaurant. Even Walt grasped that proper drinks - alcoholic drinks- enhanced a meal. I know people like to invoke the whole WHAT WOULD WALT DO, but at some point you have to step back and think that Walt might have used some common sense here and said, "It would be foolish to offer such a nice meal, yet fail to provide a full dining experience by withholding the proper drink pairings." If anything- adding drinks to the meal PLUSSES the experience.
I get that the fear is drunk and rowdy guests, but seriously people- you are more likely to have an issue with someone who had a few too many Lapu Lapu's over at the Poly over the person who had a beer or glass of wine with their meal at BoG.
