I have been several times in the SAS lounge in Copenhagen on Saturdays. With the exceptions of the early mornings the lounge is maybe 10% full. If there are too few people around, it actually creates - for me at least - a quite eerie feeling in the vast lounge area. Also the service becomes minimal ( no fresh food). I don't want to speak overcrowding a word either but Saturday access for silver members is not at all triggering that.
