I'm a PPL student, so my advice is perhaps not worth as much as that from people more experienced than me...
I am learning at Goodwood though, so I thought I'd add that it can be surprising how busy the overhead there is at times - often with traffic not in contact with the AFIS. As chevvron says, the VOR on the airfield is presumably a large draw.
Would definitely recommend landing and checking out the circuit close-up though - there's often activity on the track and some good cars to be seen, though not so much going on there over the winter.
Cheers
