Right, and that's a change, because families were initially scheduled to spend 11 hours together.
How did that change come about?

Well, as the reunions were going on, the South Korean authorities suggested to North Korea that the last session on the final day be extended from two hours to three, and the North agreed.
Generally, I could sense that the authorities from Seoul and Pyongyang worked very hard this time to do as much as they could for these elderly participants...
Not only in terms of giving them more time to spend with each other, South and North Korean authorities worked to make it so they had to move around as little as possible, and they increased the number of hours they got to spend with their relatives in their private rooms from two hours to three hours as well.
Though that might seem like a minor change, we heard from the families that their individual get-togethers were much better than the public ones -- because they could speak more candidly with each other... away from the eyes of South and North Korean officials.
