Great, thanks Karen - I've found a little pdf guide where I've marked off all the stuff I really want to see, although most of it is next door to each other so it should be pretty easy.
Hoping to get there for about 10.30 (I'm from about an hour away - going across on the train) and have to be finished by about 2 because of the company I'm in wanting to watch the football.... but then again I could always leave them to it and carry on exploring
