Danny is heading towards the hall parallel the Colarado Lounge, the wall on his right is the one Jack threw the ball against and ahead on the left is room 237. He is heading back to where he STARTED this trip but now in the opposite direction, just like the carpet has arrows pointing in two directions simultaneously. From here we can also see the all the doorways on the right side of the hall lead to rooms that are fakes - they overlap the Colorado Lounge, seen here on the far left.
