Let me be the bad guy here.
Everyone saying this is funny, it's really not. He may or may not be drunk, but my point will remain. You have to control the idiots and the first step is eliminating mind altering alcohol because some people can't handle it.
This is not only a safety concern, but an example of behavior that is not conducive to a family environment at Disney. What happens next time? Instead of climbing Mexico, let's say someone starts going around and slapping women on the bum. Is that funny? I can guarantee you it will happen. What if some creep goes around exposing himself? Then, no one is laughing and everyone is up and arms that Disney didn't "handle" it better.
I'm all for alcohol, even drugs on your own time not hurting anyone else, but not at Disney. The food and wine festival exists for one reason: Money.
It's the one thing I wish they'd just eliminate. I know people like drinking and most people can handle it, but it's the idiots like this (assuming he was drunk) that will ruin it for everyone. It's only a matter of time.
95% of people can handle a glass of wine, or even a few, but that 5% really can ruin an experience for a family that is supposed to be enjoying a family vacation. My problem with the alcohol at EPCOT is not the alcohol itself, but the fact you cannot choose to disassociate with it. You're forced to be around others who are drinking and try as you might, you can't avoid idiots.
Some people tend to be idiots at Disney anyway and they don't need an alcohol accelerator.
