Here is my scenario of what happened in that CCTV recording.
[ame="http://www.youtube.com/watch?v=3TjVBpyTeZM"]Elisa Lam Video - YouTube[/ame]
The buttons she presses on the middle row from top to bottom:
14 10, 7, 4 (the floor of her hotel room), M (mezzanine), B (basement) and finally the DOOR HOLD button on the very bottom.
Based on a clarification, she wasn't on the 14th floor, but below it. I still believe her destination was the 4th floor.
0:11 Right when she is about to press the final button on the bottom, the DOOR HOLD button (refer to the picture on my reply post), notice the elevator door about to close.
It is only then when she presses the DOOR HOLD button that the elevator door retracts, and remains open.
0:13 Elisa backs up and waits for the elevator to close as normal. However it takes too long and then she begins to wonder if somebody is outside the hallway preventing the door from closing
0:23 Elisa slowly and cautiously steps forward to investigate the hallway. She carefully lunges out quick to get a quick peek out the hallway - but nobody is outside.
0:25 Elisa steps back into the elevator, bemused at finding nobody outside the hallway. I can imagine right now, her feeling nervous and confused. She wonders to herself, "is it a ghost??" "Is somebody outside the elevator?"
She spooks her self, and backs into the elevator wall, and into the corner
0:39 she musters up the courage again to step out the elevator to see if anybody is outside. Slowly taking cautious steps since there is a hallway on the left and right, and anybody is able to hide around the corner there.
0:57 At this point, security guards in the CCTV monitor room, watching her every move via the CCTV camera in the elevator get concerned, and one of them is dispatched to take the second elevator next to the one Elisa is in up to the mystery floor Elisa is on in this video.
1:12 Elisa stands outside the elevator, back against the wall. She wonders if there is a problem with the elevator sensor and waits to see if it will close if she is out of the elevator
1:27 After waiting for so long for the elevator to work, with no luck - Elisa becomes frustrated and panics. She puts her hands on her head and gets back in the elevator as if to say "oh my god, why isn't this elevator working??"
This is when she gives a second attempt, to press ALL off the buttons again, only on the middle row to see if it will work. Unknowingly, she presses the DOOR HOLD button multiple times, triggering it on and off and on, resetting the door hold timer.
1:56 Elisa steps out the elevator again, and by this time, the security guard using the other elevator beside the one Elisa is in finally reaches up the floor she's on.
He steps out, away from camera view from the 1st elevator and calls out to? Elisa asking what is going on.
Elisa is surprised, and then gestures toward the elevator explaining her dilemma with the elevator not working. The guard asks her how many times she (still figuring out what), and Elisa uses her fingers to count 3 times.
I believe that Elisa Lam was looking for a public shower room that was vacant since the one on the 4th floor was occupied.
And now knowing that the shower rooms are next to the toilet rooms, and also being shown that there is a vent at the wall for somebody to spy on somebody taking a shower, I'm sure Elisa caught somebody spying on her while taking a shower, and then threatened the person by calling security, which led to her untimely death when the person got nervous and killed her to shut her up.
Kind of an aside, but the comment on Yelp by the girl who was ogled through the vent in the shower.. you can see how the vent adjoins the washroom next door in this video that Arnold originally posted, and how, covered in soap, it would be near impossible to run outside and stand outside the washroom door waiting for the peeping tom to come out to confront him. Knowing this, if I ever stayed there, I'd take something to cover the vent when I showered!

3:28 shows the shower and 4:18 shows the vent up high in washroom next door..

She must of been too stubborn to go back to her hotel room to get her glasses, which is why she is seen having trouble seeing the buttons on the elevator, and then taking a gamble to press the entire column hoping she'll get to her 4th floor from the mystery floor, but she unknowingly pressed the DOOR HOLD button as well.
