For those in London on 17th/18th January who missed out on getting tickets to the big Van Gogh exhibition at the National Gallery, the gallery is staying open overnight on the Friday/Saturday.
AS I WRITE THIS: There are tickets available for the early hours of Saturday morning, between 1am and 7am (see if this link works: https://my.nationalgallery.org.uk/8642/9687

It’s unique, I think, for the National Gallery to do this. And luckily Trafalgar Square happens to be pretty much the centre of the night bus network!
