A go-kart idea is great but logistics might be a bightmare. If you were to have something like that, everything organised before hand with different groups etc would be best, nothing organised on the day.

I agree though. The idea in principle is great, but think it would be tricky to find a go-kart track in central UK with a car park big enough for 150+ cars and people, too.
