Near the end of the movie when the reporter is arguing her case about going to check out the house, she says, "It's 5am, no one will be around". When they exit the lobby, bright sunlight can be seen through the windows indicating midday. When they arrive at the house, the sky is just breaking light outside.
At 1:11:35 of the film, The date on the monitor clearly shows the recording date as 05/10/2014 not 10/08/2009.
The film is supposed to take place in NY State, but when an ambulance arrives at the hotel, it has a Pennsylvania license plate. In fact, the hotel scenes were filmed in Pennsylvania.
In many scenes characters search through the hotel at night with a flashlight seeking the cause of a disturbance, often scared, yet never once turn on the lights.
At the end of the film the reporters are presumably killed in Room 2C but in any case leave their camera behind, as such there is no mechanism within the plot as to how that particular footage reaches us the audience.
One premise of the film is that the police who investigated the hotel deaths had reason to keep details of their investigation under wraps, never divulging what happened. Leaving aside the question of whether local authorities could actually do such a thing, the movie never gives reason to suggest the police knew the true nature of the deaths. Grisly and bloody as the scene may have been, to the police it would have been just another horrible crime scene, with no special reason to keep details from the public.
Who is acting as the bartender? Paul mentioned doing it during the initial walk-through, but he was unresponsive that night.
The fate of the door greeter, Sam, is never mentioned.
A few scary experiences got caught on tape, and the makers of the "documentary" edit the footage in such a way as to show the audience that in fact it does appear on the film. Yet others of the characters, shown the footage themselves, refuse to admit they see anything paranormal and don't believe the people who experienced it.
