I don't think thorpe would pretend that broken / graffiti walls in X are part of its theme..
X is touched up and repainted every year.. Last year after being open around 2 hours the walls were all ruined from graffiti, unfortunately painted wood is easy to scratch, I've no doubt it will be redone over closed season but after a day it will be ruined again.
Of course they could knock down the queue and start again / cover the walls in something more graffiti proof but thats probably easier said than done.
