I think it's equally problematic to put the kids and the patrons in that situation. In my experience, the majority of people at the resorts for example, seem to drink responsibly. But that's not always the case. Let's be honest -most people consume alcohol for the effect -the change in behavior. Bars are places where this should be expected, to one extent or another. This isn't the "forum", so to speak, to get into the finer details of the way in which this impacts, or has potential to impact the kids. Suffice to say that a great many people have an unhealthy approach toward, relationship w/alcohol. As for myself, I actually happen to be a pretty serious single malt enthusiast and I do drink at home in front of my kids. That said, I don't drink too much, or get drunk. I can't/don't expect the same from other adults (their business), so you won't find any of my kids in a bar. That's not to say that a sane parent can't find a quiet lounge somewhere on property to enjoy a few apps and drinks, but for every one of those, you've got a complete imbecile who will park their young children at a roaring bar at 9:30p.m.
As far as looking toward what may be allowed by a particular resort or bar for what one should, or should avoid in terms of parenting -this just doesn't seem like a fabulous idea to me. This was my whole problem to begin with -what we can get away with versus how to do right by our children, and the in the interest of completely self-serving behavior.
