So you mean it will be 21+ only? Parents won't be able to stop if they have kids with them?
That's the part I have no idea on, haha. I haven't really spent much time in the lounges at WDW, so I don't know.
I'm thinking "drink kiosk themed to look like a bar" is more likely. Also, I'm thinking it will be takeout cups, not glasses like a typical "bar".
That could be it. Even so, that kiosk would be pretty deep inside the TOT building. If a non-riding guest wanted to visit, it's sort of hidden.
