Is anyone familiar with the lounges in MUC? I will be flying KL MUC-AMS (in Europe Select, also Skyteam Elite + and NW WorldClub member). From what I can tell, I should have access to the AF Salon, Delta Crown Room, and the Atlantik Lounge? (Or is the Delta lounge in a non-Schengen area?) Are any of these to be preferred over the others?

Thanks in advance
