I broadly agree with JDiver's thoughts. It would be nice to have a forum where we could have threads like "Plaza Premium lounges at YYZ" or other consolidated threads.
b. Even then, there's ambiguity about access questions. "How many guests can I bring to PP lounge with XYZ credit card?", would that best fit in the PP forum, or the CC forum? What about "If I cancel my XYZ bank CC, how long can I still use the PP card?"
We can easily put this in a sticky that many people won't read, but hey, at least it'll be there.
