Let's see EPCOT is known as Drunkytown during festival weekends with ORGANIZED binge drinking, HS (or the shade Thereof) is so uncrowded I've personally never seen an issue with alcohol same is true with AK,
MK with nuts to butts crowding during much of the year totally different story, WHEN the OUTDOOR alcohol sales begin it should be most interesting as the brawls begin.
As I've said before I have no problem with alcohol sales at TS venues I even consider that a win as a I like a glass of wine or beer with my meal (depending on type of meal) heck during marathon weekend watched the fireworks from the TOTWL on BLT with a couple of mixed drinks.
That said outdoor sales is a recipe for disaster. There indeed was a reason Walt did not want alcohol sold in the park and to this day why many State and County agricultural fairs are 'dry' even to this day. it's simply to avoid the issues that the minority of people who cannot drink responsibly cause.
