Left.

You turn left and find yourself facing a corridor with a closet on one side and a staircase leading to the second floor on the other. You only have a split second to make a decision. The girls aren't far behind, so you might not get a chance to hide before they turn the corner. But at the same time, they'll definitely hear you running up the stairs. At the end of the hallway is another door slightly ajar so that you can see what appears to be a tiled floor.
