Ooohh! Was just thinking about this earlier wondering when it was.
I went last year, it was great. I wanna go this year. Like Summer Rain said they're great for trying stuff you'd never buy, I'd go to every one in the country if I could haha. Will have to see whether I can drag a friend.
One thing I'll say is it was really hard to park - took me ages to find a space. So I'd recommend training it if possible or parking a bit away. Last year was my first long-distance journey after passing my driving test :') memories.
