The more I think about it, there really is no excuse for Vader to not have his helmet on. It doesn't matter how long we make the hallway or anything. How come people can just go in and open the door without knocking or anything like that?

I would imagine that the helmet has to be uncomfortable at best, and he might want to have it off when he could. Also, only a few, select, people would have access to that room.

I seem to recall reading somewhere that Vader was experimenting with the force to see how long he could sustain himself withought the helmet for short periods of time.. or something to that effect.
