Detailed walkthrough
Before you attempt this quest, you have to turn on the power to the hotel. Head straight ahead to the casino from the lobby. There will be a security terminal in an alcove on your right and a security hologram standing right in front of you, guarding the stairs to the bar. Use the security terminal to change its patrol route to Casino west, then head up the stairs to the bar. Once up the stairs and facing the bar, in the back left corner, on the floor next to a couch is a Programmer's Digest. There is a speaker behind the counter above a fridge, so shoot it. Pick up the Casino security passcode from the bar counter next to three Sierra Madre chips. There is a first aid box beneath the speaker, and a vending machine code for wine on a shelf near the fridge. Enter the door next to the fridge.

You need to head down the right-hand side corridor, but it is being patrolled by a security hologram. You can sneak past him, and disable his emitter, or you can change his behavior with a security terminal.

If you go straight ahead and up the stairs, you will find a door to the kitchens, but it is locked. At the end of the corridor is an open door. As you approach it, you will hear the familiar beeping. The radio is located in the room next to this one, on top of a tool cabinet on the left side of the room. This room also contains an autodoc which can be used to completely restore you to health. The room with the open door contains a terminal which has information you can read for the challenge History's Sake. On the wall next to the door is the very easy security terminal, which you can use to change the behavior of the security hologram in the first corridor. If you set him to guard the bar entrance, he will have his back to you, and you can access all of the corridor.

Now head down the corridor and into the room on the right. Here there is a door to the cashier’s office, and a hard terminal that opens the electrical closet and can reprogram the second casino security hologram to guard the cashier window. The hologram emitter for the corridor hologram is in the corridor beyond this room, up on the wall behind you.

Head back to the bar area and jump off to your left. You can either change the security guard’s behavior to patrolling the bar, or disable its emitter. The hologram emitter for one of the casino security guards is on top of a beam jutting out from the bar. If you look right and up a bit, you can see it and disable it. The electrical closet is right at the back of this bottom floor area, guarded by a hologram whose emitter is right behind where it stands (if you have problems destroying this emitter, just throw a grenade past the hologram. You can also sneak past this hologram. Even if he is alerted, he will be disabled when you activate the power). In the electrical closet, flick the switch on the right hand wall to give power back to the casino.

At this point, you will receive the quests Last Luxuries and Curtain Call at the Tampico. You can do the three quests in any order, but as Elijah will tell you at this point, you must deal with all of your companions before you can move on to the final quest.

Exit the closet. The security holograms will be de-activated, and the casino will be full of hologram dealers. You can now gamble here if you wish, and there is now a cashier who will exchange pre-War money for Sierra Madre chips.

Go back to the lobby, and enter the Cantina Madrid. Disable the speaker on the top left wall. The marker points to an emergency maintenance key sitting on a clipboard to the right as you enter, so pick it up. You can hear Dog and God arguing with each other, but you can't reach them from here. Head back into the lobby, and from there to the casino.

Head upstairs to the bar again, through the door behind the counter, and up the stairs. Use the key to open the door to the Cantina Madrid kitchen. There are three gas valves you must shut off before you can leave this area. If you are spotted by Dog, he will set off the gas, killing you both, unless you initiate conversation with him.

If you pass a Speech check of 50, you can tell Dog to remove his collar. This will kill him, and you will need to get out before yours goes off as well, so you need to turn off the valves first if you plan to use this option. If you pass a second check at 75, this allows you to subdue Dog, which kills his character but leaves God alive. Passing a third Speech check at 85 allows you to merge both of them together. There are of course other options, such as killing God and leaving Dog, or simply killing them both in a battle.

If Dog dies either by battle or by jerking his chain, make sure you loot his body. He has the Maintenance Pass that will allow you to open the sealed doors.

Any option completes the quest, but you still need to turn off all three valves before you can leave. As you enter, the first gas valve is on the right hand wall pretty much straight in front of you. Head into the door on your left and the second valve is on the right hand wall with all the cabinets. The third is at the back of the room, in between two doors and near Dog's walking route, so make sure you aren't seen. The second option is to talk to Dog. If you get the chance, sneak up on him and stand up to talk.

Note: There is a dramatic change to Dog and God’s ending if you merge them together. They will not remember you but will mention having a sense of gratitude toward you. The merged personality will not attack you.

Bugs

 * Under some as of yet unknown reasons, the emergency door to Cantina Madrid that is supposed to lead you to the kitchen, takes you back to the room where the emergency door key was in, giving no way to enter the kitchen and completing the quest. This can be solved by starting and completing some other quest about dealing with the team members instead, then returning to the casino to enter the kitchen of Cantina Madrid.
 * Waiting in this area may cause Dog to die and set off his collar as well as yours. The collars go off almost instantly when re-loading an autosaved game. It is advised not to wait in this area.
 * The "note" listed in the above section about the speaker located above the fridge outside the room is far more than a simple note, it's a catastrophic bug. It seems entering the room without shooting said speaker guarantees that every time the game reloads your head promptly explodes 10 seconds later in a loop. This is the because the entrance door is sealed shut until the 3 gas valves listed in the quest log are closed. Should you have not saved manually for many hours prior to this event, this "bug" has the potential to wipe out an astronomical amount of game play time and can lead to symptoms like an ever increasing hatred for Bethesda, and snapped game discs.
