Detailed walkthrough
The quest begins after you have dealt with Dean Domino and as you enter the Suites area from the main lobby after killing a couple of Ghost people in the lobby. (note: on my playthrough, I took this quest after restoring the power to the casino. I didn't look for any other crew members, I went straight to the suites, and did not see any ghost people)

When you first enter the corridor you have a choice to go either left or right. Going left will reveal a small poisonous cloud and a little further on a locked door of average lock and an open room which will lead to a room with walls destroyed so you can enter the locked room without picking the lock, but you will encounter a hologram which will attack if you get close, so to get rid of it you need to enter the room it is in and find the bathroom which is in the corner of the room and close the door you will find the emitter you need to get rid of the hologram. Once this is done progress through some rooms through the broken walls and you will find caved in corridors follow the corridor past poisonous clouds (easy to avoid) and there is a room on the left enter it and it has broken metal shelves and you will see a radio on top of washing machines disable it, and find the terminal which has the maintenance key and access the terminal to override the emergency door. There is another terminal to the left of the first one and it requires an easy hack and this will disabil the hallway speakers and give you a recipe and hologram code.

Leave the washing room through the door on the other side of the room and you will be back in the first hallway with the maintenance door open, go through and follow the corridor to the right and open the door on the left, the other rooms contain holograms that will attack if you get close so ignore them unless you want to explore. But to continue you will enter a room with lockers and a terminal of average locking which will make the holographs friendly, hunting shotgun and ammo. Turn around and you will see two doors the one on the right will have ammo and lever action shotgun. the on the left will lead you back through the suites, but if you accessed the terminal you will have change the security holograms and they won't attack, in the first room pick up the password on the table and keep going forward until you exit to find a corridor with a vending machine on the left. Go forward and on the right will be some double doors which is Vera's and on the left you can access her private elevator, but go right to find Christine. She explains her story and you don't kill her and shouldn't need to, but she gives you a key that belonged to Vera. The quest ends.
