The staff at the palace, have a bench or two in the passage where the elevator was situated, for people watching the video that they show on a tv. So you cannot see anything, at least, neither could I.
What you can see in the corridor, is the old entrance markings where the wall joins the floor of the door leading into the Maple room, opposite the door to Nicholas' new study.
As for the photo of the corridor, it is pasted into my album of my trip, and I do not have an idea where the negative is. I'll search for it. I also took a photo of the the mostly glass and wood "door box" (not sure what you call it) that covers the big door in the Vestibule towards the outside. Bob, if you are coming this way, you are most welcome to see the two photos.
Do you have clear detailed plans of Alexandra's dressingroom/ bathroom area?
