I'm planning on going Saturday, but as I'm still recovering from a broken ankle I'm not sure how easy it's going to be. I certainly don't fancy crowds while on crutches 
From past experiences at Harrogate and the Midlands shows it gets a lot quieter around 3pm. If you're wondering why I'd bother while on crutches it's because we make a weekend of it and the hotel is already booked. Might have the wife in tow though so it might be a flying visit. I can just imagine the comments "Have you seen enough yet?".
I'll be easy to spot on crutches.
