While in London we felt obligated to witness of the changing of the guard at Buckingham Palace. Our visit was during October and the crowd was still pretty big. Having been our first time we were not sure where to find a place to stand but still managed to see a fair bit of the ritual.
Keep in mind if you go that there is no ideal spot as so much happens it is impossible to see it all.
