That's OK. I think you can fit 4 in a car so you would take up 2 cars. Also, I think each car has 2 rows. There will be a front seat that seats 2, and a back seat that sits 2. Hope this helps.
Yes some cars have 3 rows. Also depending on the size of your party 3 can fit in one row. We did this with me, DD (4.5) and DH and fit in one row very comfortably.
