Long before the NW move...
...I HATED being in the LAX CRC (now SkyClub) at night because it was ALWAYS packed! Their were (and probably still are) A LOT of red-eye flights leaving LAX, not just Delta but other SkyTeam (Air France and several AeroMexico) so the lounge was always full.
What makes it worse is that CRC/SC is basically one large room with no real partitioning AND the TVs are ALWAYS blasting. I asked once to have them turned down and the attendents said it was physically impossible to adjust the volume!
