I feel like I should confess - Hi I'm LumosQ and I've been drunk in the Magic Kingdom. A few times, actually, after a nice dinner at V&A, with the wine pairings, then toddled off to the Magic Kingdom afterwards for a lovely end to the evening. Or a few post dinner cocktails at Sams / one of the many other lovely bars at the hotels before heading back in. FWIW, I've never vomited in a bush / on a ride / been rude afterwards. Haven't seen anyone else do this either and can't imagine we are the only people who like a drink back at the hotel before returning to the park.
Maybe its because I'm European, but really, whats the big deal? A drink with dinner does not mean you're going to be going to be channeling your frat party past. And lets face it, we have all seen the parents yelling at kids that probably could do with a glass of wine to mellow out a little
DAK, HS, even the *other* parks all serve booze and I've never had an issue seeing inappropriate behaviour. We only had an issue with rude / loud people at DAK once but it was 9am so unless they got a start at the hotel it was personality driven, not the fallout of imbibing a few watered down cocktails.
This is not going to impact your trip. We go to
Disneyland Paris a lot, where you can have a drink with your "quick" service meal (when you finally get through the line - goodness do I wish their culinary team would visit WDW for a little advice on the speed of service) or in the sit down restaurants, and have never seen anything that would be a concern (apart from sober people who push and pull during parade time - truly the worst place to watch the parades
). It will all be fine, honest!
Walt would have moved with the times too.
