Can we do a quid pro quo? Disney gets rid of the bars and adult beverages, and Vegas eliminates the Disney-fied shows and "family entertainment" that are ruining my drinking and gambling out there?
I agree with the comments above - Disney is realizing (as well it should) that there are significant numbers of adult guests who visit the parks without kids and who would like to have adult options. Those options aren't detracting from the overall family atmosphere or changing the character of the parks. No one really goes to WDW to get drunk - particularly for what it costs for a single drink (disclaimer: there is the exception for Drinking Around the World in the WP, and I know there's a lot of pearl-clutching about that topic). Disney wants to provide those adult guests with their own experience, too. I think we can all coexist.
I'll also add that, as a solo traveler on occasion, the bars and lounges are perfect for me (and I don't soak up any of those ADRs that families want). As soon as I get to AK in a few weeks for my next solo trip, you'll find me sitting at the Dawa Bar with a bloody mary enjoying the Harambe drummers. I mean, I COULD go grab a slice at Pizzafari and nibble it in the corner by myself - but that doesn't exactly sound like the best way to kick off my visit (disclaimer: even the QS options in AK sell alcohol - it's not like someone even needs to find a bar if they want a drink).
