VS discount with VH

As a member of VS frequent flyers I know that I am entitled to a 10% discount off any booking with V holidays[oo]
Next year we are looking to fly to Hawaii via SFO as 3 couples. The other 2 couples have never flown VS before and to be honest no one can get near the cost of the holiday that VH are quoting.[y]
VH have told me that we will all get the 10% discount providing the booking is in my name etc.
My question is if the other 2 couples join frequent flyers will they get the discount in their own right without having taken a flight, but by just by being FF members.
Or do they have to have had a flight with VS prior to the holiday to get the 10% off.
Regards
Paul
