(Have you got the right school Wayne?)
If that's the place, I did the weekend course last year. The week course starts with the weekend course and then when most of the students go home, a few stay for the rest of the week. I think four stayed when I was there - I wish I had done, but my weekend was a wedding present, so it was out of my hands. Great wedding present though!
Anyway. I enjoyed it and learnt a lot. The chief instructor Ged, was very knowledgeable and easy to get on with. There were two other instructors when I was there. I'd recommend them. PM me if you want any more info.
