I already know, but even if you can walk through the doors.. what then? just sit in the captains room and pretend to have a cup of coffee?
HOLY SH*T that'd rock! Be all like
"Computer, coffee, b*tch!"
Then you strike a crazy anime pose and scream
"QUICK EMBIBEMENT ATTACK!"
And drain the cup. Then the cup's like
"Woah! Holy sh*t, man! that's some crazy stuff!"
Or something.
But seriously, for immersion's purposes it's quite important to have these rooms, there could be first person missions where you're not the captain, for example. Going to talk to Janeway in her ready room.
I'm not saying you have to model the room, that can be done later. Just that for immersion's sake, perhaps you should consider making all doors on all bridges double sided and functional from now on, they can stay locked until there's something behind them.
Immersion or BP can be used later to add rooms behind the doors.
