I just couldn't see children on them screaming at their friends down below being something that would be ok with anyone and yet that would happen ALL the time. Or the kids would find something to play ball with. I have a kid that would do just that.
They could do what they did on the freedom class and have them with a glassed off view of the interior with a bench to sit on, which protects against this, but they would probably have to sell those rooms cheaper? Time will tell, but I am not for it even though we really liked the freedom class ships.
