You step out of the turbolift into one of the coolest hallways in the whole cube: hallway B1. This hallway is noted for it's doorways to the bedroom (located to your left), the holodeck (to your right), and of course, a freaking tritainium bulkhead (located in front of you).

Punch bulkhead!
The bedroom.
The holodeck.
Look at the computer panel near the holodeck door.
