In several of the parks, yes! Hell, getting drunk off of “drinks from around the world” at Walt Disney World’s EPCOT is a popular theme for adult guests nowadays. However, I’ll mention that Disneyland is still quite restrictive (though their neighboring park, California Adventure, is not and fully embrace alcohol sales).
Why? You’re disappointed with the explanation? Disagree with it? Or you don’t like its somewhat informal tone? I thought it was well written, enjoyed the information / humor, and can respect the explanation.
