Hi Guys,
We changed from the usual 7 seater to an 8 seater Ford Van, it seems the 12/15 seaters are the same vans with an extra seat in which as you said takes the luggage space. It turned out we had 9 there, for one of the weeks and ended up getting a Dodge Neon also, so would have been better to take 7 seater and a car!! My irish DL only covers driver+8 so a 15 seater was out for us. It was great to have the two cars to be honest, I could do stuff with the house and Marianne took the inlaws to parks I have had enough of
