i was asked the question & didn’t know the answer;
with 2 people in the car & only one is a member (me), does that mean the passenger (wife) has to pay an entry fee or does the card get us both in?
Hi Joe
I dont think you will be the only one with this question,as i myself will be coming in both of mine ,which will mean myself,my good lady,and my two off spring 13 and 9???
Regards
Ah yes, bit of a problem there, hide kids in the boot. 
still, it’ll be a good trip over ------- snake pass?
As members on the National Committee, and Chatsworth Organising Committee had various views on admission, we sort guidance from the clubs chairman, John Cookson replied -
One membership card gets one
car plus passenger (ie up to two people) in for free.
One card will
also cover a genuine parter or spouse in a separate car, plus
their passenger (ie up to four people) provided they turn up nose to tail
sothat they can explain that the one card covers two cars.
Note that you
can have joint membership, with a partner/spouse named on the card - that’s
preferable but not compulsory (for now).
Offspring/nieces and nephews,
friends, fans, hangers-on and anyone else will need their own membership
card(s) if they are bringing in
additional cars! Or pay £2.00 on entry.
Brilliant, sorted, thanks for clearing it up. 
Sweet! I’m in.
Ok so what if it’s four people (2 x2 joint members) and a baby? all in the family car? 
I’m only asking because my car is being used by one of the traders, so we a scrounging a lift off my daughter who is also a club member but isnt bringing their MX because the baby is coming too.
