ZFT, there are perfectly good bunks for us to rest in.
From a passenger point of view I would prefer the blinds to be down to provide better contrast to the IFE screen. Also, when blinds go up, other passengers wake up, which causes disturbance when I am trying to sleep. Eye-shades don't really work for me, either.
As crew, I would keep the blinds down for the benefit of the whole cabin. If everyone else is asleep, I would encourage them to be left down. If everyone's awake, then fine.
Your comments on crew rest however are uncalled for. Unless you've done the job, on this route, you can't really comment. This forum is not a place for passengers to have a dig at crew. You have Customer Relations for that.
