I didn't expect to have been as consumed here as I was. Six hours went by verrry quickly. I am a little methodical in my perusal, so time does go fast.
I would advise paying for the audio guide and start from the very beginning working your way from the Tudors to the 20th Century. The narrative is both illuminative and engaging with a number of laugh out loud moments ( at least I did )
Human nature is unchanging across the centuries in peace and war , love and hate.
The artworks are exquisite as are the subjects and historical snapshots. Do pay attention to subject, content and artists.

Beautiful.
Go early and enjoy.
