I'm not confident there will be a massive "change" to what they have going. Too many BIG changes have already occurred that would be too difficult to revert back from. If there is any adjustment, it may be selling mixed drinks in the built bars apart from Finn's (I guess Moe's is the only other option?). They may add wine to the pop-ups.
From an accessibility perspective, alcohol is still readily available. The pop-ups have beers and the pre-mix signature. If a guest wants to wait in an hour-long line to get a Long Island because they don't want to drink anything else, that's their choice. Universal isn't obligated to put tequila on every corner.
As an avid drinker and outside observer, what they've done is create a pretty effective middle ground. It may not feel like it because it's such a change from what's normal, but alcohol is still widely available. The hard stuff is just being much more controlled. I'm far more intrigued by the why, because I think what they've done is fine.
It's just Marketing's fault it wasn't announced in a timely manner.
