When Ofelia leaves the truck and starts walking along the border wall, she is walking east - which makes sense since New Mexico is her destination. In her next scene, where she finds the break in the chain link fence, she's walking west, which would make no sense.
Travis looks out the hotel window from hallway outside of his room after hearing a commotion and sees the guys that were with Chris being run out of gate of the hotel. He is on 2nd floor which is how he can hear commotion from the room when he does this. You can see the landscape and people are only one floor below window. Then they show Travis running down at least 5 floors of stairs
to get to them....
