A large convoy could be 'interesting' to say the least - but it would be a right-turn towards Portbury village (from the services), cutting across traffic, so i would expect it to fragment... Further fragmentation in the village itself (especially at the narrow bit just after the sharp right onto the hill)....... If people try to catch up it could go wrong, then you have a right turn at the top to get to the showground (bad enough at the best of times with a limited view to the left, let alone when you're trying to keep up with your mates).....
....Having been seen to pour oil on the idea, it could well be an excellent run if the drivers do it well (as I'm sure WE all would)....
....just remember - familiarity breeds contempt - stay safe
