I’m indifferent about it. I’m not opposed to alcohol being served in DL at all and like that there are so many options at DCA. However, I likely won’t spend the time and money to eat at BB just for a cocktail. I usually take a midday break at the GC lobby, Trader Sams, or one of the DTD restaurants for appetizers and drinks already.
The lack of alcohol is certainly a deciding factor when choosing between Carthay and BB for me. In fact, I have only been to BB once in 20 years, and that was not planned by me. I always think about heading back while cruising past it, but I never quite get motivated to actually follow through. Overpriced or not, it would probably still be cheaper for me than a trip to Trader Sam's. I will definitely be making a long-overdue return visit on my next opportunity specifically to try out the drinks (which I suspect I will be needing more than usual on my next visit).
I've never been to WDW, so I have no comment on that. However, the one and only time I saw a group of obviously sloshed adults was in line for Pirates when DL was dry. Never in DCA, or DTD despite seeing many people with a drink in their hand. Frankly, it was alarming, and when I mentioned it to a CM, all they did was separate my family from that group. While relieved, I would have thought a group like that would have been stopped before potentially causing a problem on the ride. In any case, I have no problem w/ finally being able to have a decent drink in BB.
