I was going to drop this but........... as I said earlier, there were about 5 people in a 1400sqm lounge. An nobody anywhere near the kids area except the lounge dragons.
And why the hell would you put a Jetfriends Kids lounge without any partitioning in a business lounge with a DVD player, computer games and toys if you wanted no noise and it to be a library???
Kids make noise. Some scream, some sing, some just talk loud. They even have screaming kicking fits on the floor.... Accept it. If LH want a library. Move the kids area somewhere else, or put some glass up!
I totally accept that some people may not want to hear any kids whatsoever. (indeed I don't sit in the kids area when I travel). In which case there must be 6 other lounges at FRA as a gold card holder at least.
