I love having my birds their own room.They have playgyms in the kitchen and the living room.They are out on them much of the day.But when its time for bed...they can go to their room and I don't have to wory about cage covers or the noise bothering them.Close the blinds and shut the door.
We like to have parties quite often.We do poker parties and bon fire parties when the weather is warm.Every other weekend or so there are people here.Dodger is fine with lots of people...my macaws however have issues and get very nervous when people are over.With their own room...I can remove them from the situation situation and they remain calm.
I recently put a lock on their door...to make sure noone sticks fingers in the cage

Because the birds can and will bite.
Having a seperate bird room has been GREAT for us.
I also think it gets them more out-of-cage time then they had before...maybe because of the guilt you mentioned...but they spend darn near from morning until bedtime out.
