I think it’s ok to sleep on the landing if the bedrooom doors left open so they can still chat, I could do it with dd’s room as there’s space by her bedroom door.
I think you dd is being a bit unreasonable saying ‘it was boring’, my dd and her friends would be happy with 2 takeaways in one day (subway and pizza) and being left to their own devices to entertain themselves, I don’t think kids that age need activities sorting for them.
I think your dd maybe exaggerating and that the door was left open and your dd was free to go in and out as she pleases, just that sleeping space was tight so it spewed out the door onto the landing.
