We eat at Sci Fi every time we visit WDW. We too are a family of five. On our last visit, our girls were 14, 11, and 9. Our two youngest daughters always sit in the front row. Our oldest daughter sits in the middle row by herself. My husband and I sit in the back. The seating arrangement works for all of us. We're busy eating and watching the film clips so being able to talk easily is not super important for us at this restaurant.
