I've narrowed down my search for a new Pacifica to the Limited trim. I am considering getting one with the 8th seat (no sunroof due to seatbelt placement). My question is how useful is the 8th seat for seating teens and adults? We also have a Toyota Camry and my kids fit fine in the back seat. Although we are a family of 5 I like the versatility of being able to take 8 adults. Is this realistic with that as the 8th seat? Also how well do 3 adults fit in the back seat? Thanks in advance for any advice.
