Personally, I'm not concerned with people getting drunk at BOG. I've never seen an intoxicated person or a group of intoxicated people at WDW, not once during any of my trips, ever. This has nothing to do with anyone wanting to enjoy a drink with their nice meal in the park. I don't care whether Walt liked a drink with dinner, or a cigarette in the park.
However...I personally do not agree with the decision to serve alcohol at BOG. I completely understand how, from a financial perspective, it makes sense. I think that it's a great move for the Walt Disney Company, and it's probably the move they should have made years ago. And I get that the parks don't have to stay exactly the same as they were before; Walt is dead and we can never know what he would think of adding alcohol to the Magic Kingdom. I have no problem making reasonable changes with the parks.
The reason I am against introducing alcohol at BOG is because of Walt, however. Walt made a big deal out of keeping DL dry. In fact, Club 33 (the oft-quoted example of why the Florida MK can serve alcohol--if Walt's original park can serve it, all the others can) has its own seperate address apart from
Disneyland just for its liqour license. It was meant to be a private, exclusive place for Walt to entertain investors, and has since become a highly exclusive, members-only club (that admittedly is a lot less exclusive since members can make reservations non-members, but I digress). My point is, simply, Walt designed both DL and the Magic Kingdom to be dry parks. Walt was part of the design of Epcot, and we have no indication that he intended Epcot to be dry. We do know that he made the decision to make the MK an alcohol-free zone, and we do know that he took the extra steps of giving Club 33 its own address just to maintain DL's completely dry status.
Do I think we need to keep absolutely everything exactly within the boundaries of Walt's original design? No. Change happens, and we have to be willing to change with it; we don't know how Walt would feel about any of the massive changes being made to his parks. But when Walt's wishes were as well-known as his wishes on the MK being an alcohol-free park, is it such a big deal to stick to his wishes? We don't know that he would now disapprove of MK serving alcohol--but we do know that when he designed the MK, Walt wanted it dry. Maybe, seeing his park today, he would change his mind--but we have no way of knowing that. With every other park and restaurant not in MK able to serve alcohol, is it really that big of a deal to leave this one little part of the MK as Walt designed it?
