>The sun was rising behind the hotel. It is currently to the right.
Nan considers that if the sun was rising behind the hotel, and she's been going further and further back in it, then she's been heading East. Therefore East must be to the right of this room.
She moves the small stand and sure enough, there's another outlet on that wall.
Now for one final question.
Did the order mean "east-facing" as in "on the West wall" (facing east?) or "on the East wall" (when facing east)?
