You need to bring your sniper rifle with you on this one. First, go to the receptionist desk on the right to get your room key. Then go up the stairs, and onto the left elevator. Wait for the door to close, then climb the hatch. Wait on top of the elevator until your first target comes in, equip the fiber wire, and strangle him. Take his keycard, get his suitcase (it fell back into the elevator), climb the hatch again, and leave it there. You need to come back and get it when you're done with everything else. Get out of the elevator on the eighth floor, go to the elevator on the right, wait for the elevator to get there and press the lobby button. When the elevator is on it's way down, climb the hatch and wait for your next target to come out of the casino. He makes his way to your elevator. Wait for the door to close and the elevator to start climbing to strangle him as well. Take his keycard. Don't forget your rifle case. Wait for the elevator door to close when it gets to the seventh floor to climb down. So as to avoid suspicion. When it closes, get down and press the "Open Door" button. Get out and go to the room that the agency rented for you. 701. Go out onto the balcony, unpack your rifle and put it on the ground. Now go down into the casino, head right. Go to the first set of double doors that you see on the right wall. Go through them. there will be another door to your very left when you enter that room. Go through it. Walk straight down to the middle of the hall to the first door on your right. Go through it. You'll be in a bathroom. There are only two people that enter the bathroom. A civilian, and one of the shiek's guards. Wait until everyone is out of the room so you can pick the lock of the door on the opposite side of the room from where you walked in. There's a freezer where you can store a body in there. Don't go in that room though. There's a patrol that comes in there every once in a while. If you time it just right, you can sedate the guard in the bathroom, take his clothes, and drag him to the freezer in the next room without anyone seeing. After you get the guard's uniform, get outside to the hotel, get onto an elevator (it doesn't matter which), and go up to the eighth floor. Use the keycard that you got from the first guy you strangled to get into his room (which is guarded; hence the guard uniform you had to snatch). Go into the bedroom, and use the phone on the desk to call the shiek. Now you must run. To the elevator, down a floor to the seventh, to your room (701) out onto the balcony. Get your sniper rifle and aim down into the little outside square surrounded by the casino. The shiek will come out there and stand to where you can just manage a headshot. lol. Now you can head back out of your room. Get back onto the elevator to the left. Don't press a floor yet. Wait for the door to close, climb the hatch, and grab your payment suitcase. Climb back down. Press the lobby button.
