Reading through all three pages of this thread, I see that people were living in the palace as late as 1915. And yet, someone also says that the main block of the palace was mostly left as it was in the early 1800s.
Did the more recent residents live in the wings? Surely the palace was renovated or "modernized" to make it appropriate for a 20th century lifestyle. For example, bathrooms must have been added. Does anyone know where the bathrooms were or are located? Or what other changes were necessary to keep the palace livable through the years.
Also, while looking at the AlexanderPalace.org's pages on Pavlovsk, I noticed that the "floor plan" link is broken. I would be very grateful if someone could post the plans. I have been able to find only very low resolution plans or highly inaccurate ones.
