I will be there over the Easter weekend. Not sure of dates but usually at that time around 40-50 cars go over from the UK (mainly Fords) and it makes for some fun driving there in convoy as well as round the ring. 8)
Plus there's lots of people out and about in the evenings.
Easter is one of the busiest times, and the weather can be very changeable [-o< , every year I always say to myself I will give it a miss, but I never do \:D/ . Easter being on April 6th ( Good Friday ) I will have to be very, very careful, as I go on holiday the following week :-D
