I don't think it is not drinking in front of the kiddos but rather end up with a drinking around the world atmosphere at an event marketed for children. I didn't see anyone falling down drunk at the Star Wars events and it was the same thing with the drinks being offered in the Frozen Frenzy. But maybe there will be a parent or (two hundred) who are just so completely ready to "Let It Go" that they do indeed Let It Go! lol Honestly, you can get drinks at HS so those people who would enjoy a drink will do that regardless.
I think if I hear that song one more time, I'm going to need a fifth of vodka to chase it with.
