I am a biker, so I am asking out of ignorance -- how does a flat terrain cause more problems? It would seem like the opposite. As for your husband, he will find plenty to do with the kids, because the Katy was laid out with towns every 10 miles for the purpose of bringing on water for the steam engines. Lots of local history, and your 8-year-old could read up on the Lewis & Clark expedition and follow their (your) progress along the trail. The rest of the family can even take short day hikes with you, which is much more difficult to do on the Appalachian Trail.
