Follow the red carpet through the room with rope stations on either side. Exit that room through the open wooden doors and continue forward until you reach the intersecting red carpet. Stop there, on the red carpet looking directly at the "Viaggio in oriente" display.
Walk through the room and past the ropes. Stop just inside the double doors.
Walk down towards the opposite end of the red carpert, and throught the doors. Stop once you reach the red carpet that intersects with the one you are on.
