We have had a window suite on the Grand twice. . IF the door at the far end is left open too long, which happens on occassion, I have smelled some smoke in the hallway. Very faint. It has never gotten in the cabin.
I'm guessing the cabin steward left the door open while working. I have closed it a few times.
Yes you might have some smoke smell in the hallway. Sorry guys. It does happen but again never smelled it in the cabin.
