I have given some passes to my friends who are constantly traveling with me and I have had some degree of success in gaining entry for them with the passes. In Rome, the Giotto Lounge (AZ) allowed my guest to enter by surrendering a one day pass. That's the only place I can say for certainty that it's happened.

I however have successfully used my PClub membership to enter not only the WorldClubs, but also the Crown Club/Room in DFW, the China Airlines Dynasty Lounge in Taipei, the JAL lounge in NRT and finally the Amtrak ClubAcela at Penn Station. The only drawback that I have ever experienced is that most of the overseas clubs/lounges do not allow for guests (except the WorldClubs). For your convenience, I have included the link for the recipricol club agreements:
