We wanted to visit the KLM lounge in IAH last Saturday (free with lounge club membership), however the lounge was so packed at 11 am that we couldn't even sit together with the three of us. Lots of families with small children too. We quickly walked up and down the lounge to check, and I can honestly say, a random seat at an empty gate in front of the lounge was more comfortable than sitting in that packed lounge.
