I would suggest a trip to your AME for an eyesight test. At least one chair in the background....
I think it's a very nice touch to see the kids sitting on the floor as it gives the impression of calm and saftey....
You wouldn't set your kid down on the floor in T3, lest he/she was run over by a trolley, bowled over by maruading masses meeting/greeting/checking in or got stuck to the sticky carpet....
Good advert BA !
