Rome off the beaten path options for all ages?

[twruger]

What are good sights/itineraries off the beaten path to avoid the major Rome hotspot crowds?  We are  docking in Civitavecchia late June and travelling with a group of 7, ages 12-68.  Ok with DIY and trains.  Max 9 hour outing.  Avoiding throngs of people will be of more importance than seeing Coliseum, Vatican, Pantheon, etc.  

 

Suggestions?
