how come it's acceptable for them to just rock up at Pemberley and get the grand tour from the housekeeper, and wander round the grounds? I mean, what the hell?!

Lol!!

In those days those homes were very much treated like stately homes bow - open to public viewing apart from the living and servants quarters. It would have been normal to show visitors round - many people of gentry felt it was giving back to the people a little who were less privileged than them.

Do you remember in the lion, the witch and the wardrobe, when the children have to hide in the wardrobe because the housekeeper is showing groups of people around?
