What is the point of this thread? Unless you are planning RTW trips based upon the location of lounges, you have little choice in which lounge to use. At most airports security limits you to one terminal at the airport, so you cannot lounge hop between terminals. And there are only 5 lounges in the world that are noteworthy (in OW, and 5 outside of OW). The worst hotel tends to be better than the best lounge (at least when I travel). The biggest mistake you can make is selecting routing based on lounge availability -- you are bound to be disappointed. I confess to having picked BA at times solely based on lounges at LHR, and it was a bad choice.
