Please let us know what you think of it. Only one I've never been in.

Late to the party here and I see it is no longer an issue for you; but for quiet I recommend B. My biggest reason for maintaining access to the AAdmirals Club is winding down after a flight. B seems darker and less hurried than A, C, and D in a good way; so it works well for that (even if my first selection criteria is "closest to arrival gate", with a distant second being "where's my car")? B has the best ramp view which is a plus for me.

The downside, or so it seems to me, is less serving space and fewer food options. Last two times I've landed at B it has been two soup buckets and "build your own salad", but no hot entree. (Was pretty good, such as any of them are. But by then I just want a little edible food, a little quiet and calm, followed by a quick trip home).
