Many fans of the film have noticed that the window seen at the beginning of the film, in Mr. Ullman’s office is an impossibility. Scenes that take place near the end of the film show that a hallway should be behind that office. Not the outside.
While this can be written-off as a continuity error, it further shows the mind bending space of the Overlook Hotel. The Hotel itself is a lot like a metaphorical maze the characters are going through. Leading up to the actual maze at the end of the movie.
