I was just wondering if my husband actually rents the car and pays for it when we pick it up, is there any problem with my brother-in-law actually returning it? We fly in the same time as them, but my bil and sil have to leave before we do. We thought it would be easiest if they could just return the car. It seems like the rental car companies usually just scan the paper work and check over the car, but I've always left that part to someone else so I'm not sure. We'll still have a ride to the airport since the in-laws are driving to meet us there so that's not a problem.
