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.

It all depends. If its all adults probably not. But if there are children in your party you might be able to make it work.

We had 3 adults and 3 kids. The 3 kids sat together, and definitely could have fit 4 adults with 2 in each if the other 2 seats.
