Thank you all for your help. I think we will go for the South Lounge and then move to the B lounge and try to guest one of my companions in each one. I don't see any restrictions regarding using several lounges with my AS status so I guess that should work. We won't enjoy the lounge experience together but that is better than nothing. I will try to figure out whether someone is in the mood of guesting one of us but I don't quite like asking for favors to people I don't know
