I should put a disclaimer into my posts that they're anecdotal, but we've been to Disney 16 times since 2007, when we first noticed the large groups. I wonder if Disney keeps track of drunk incidents.I don't buy into this being an issue, but I will say by Disney's own design, they get people drunk at their Food & Wine luncheons.
You have a four course tasting with four drinks - be they tequila, wine, etc. Plus there's usually a welcome drink. So that's 5 drinks over the course of a maybe 90 minute lunch? I know I'm pretty well buzzed after those. (not complaining - got my money's worth.)
