I would love to go, either with Radical or GT40, but am not sure whether I can justify the expense at the moment. Have been for the last 2 years, last year with the Radical. The new garages are very spacious and well equipped with loos and power points - I would guess they could accommodate some 6 cars with room to work on them. Also they can be locked overnight, so you can leave the cars there. Last year we even left our covered trailer in the garage overnight.
When we planned to combine a visit to Spa with one to the Ring as well the year before last (just another 65 miles or so) they rather inconveniently had a 24 hour race at the Ring, which with practice and the race meant that it was not available for several days. As you probably know, it is road legal cars only (or cars that look as though they are road legal!) on public days at the Ring.
Anyway, I will let you know. I must say I am very tempted to have another go on the best race track in the world. Also the Goldtrack days are well run and informal (you don't need the drivers briefing again on the second day) and there never seem to be a large number of cars on track.
Where are you staying, by the way?
