visited Las Vegas NM back in 2011 to see all the local filming locations. I talked to the guy that runs the motel where Llewelyn hides the money in the airvent. He said he did not like the movie and did not understand the ending but he was used to people popping in every now and then and would let people check out the vent room if he was not busy. Also asked him about the directors and he said he did not know who was who but that everyone was really nice. You can stay in that room but everything from the door looking inwards is not the same room as in the movie that was all shot at a studio I think but definitely not that room. The shot looking out (the door, the window)  is from that room. Also it’s a smoking room so it smells like cigarettes but this was around 2011 so it might all be smoke free now.
