You will also find that Elstree has 6 (?) variable ccts. Continuity when working up to fist solo may be a little difficult. I've said it before, try Denham. It's only a couple of junctions around the M25 (20-30 mins?). If you're going to fork out a few thou on flying, make sure you do it in a good environment. There's no harm in jumping in your car and going for a look
Socially, I have found Elstree to be fine. I did a presentation in the aero club a while back and was plied with free beer throughout the evening.
