3rd row has 2 seats. Decent space for kids and short adults. Anyone tall will have a hard time sitting through long drives. The middle row seats can all be moved forward to create more room in the 3rd row, though. Middle row seats also recline back and incline forward.
With the 3rd row seats up, I am able to fit the uppababy cruz stroller alone with two small carry ons (20 inch spinners). There is definitely room.
