That would be my main concern. I know I-95 is rough all that week between Christmas and New Years, I'm sure I-75 is the same. Stop and go traffic is tough with kids. If you had a Motorhome, maybe not so bad, but since they'll need potty breaks more often, that means getting off the Interstate or trying to pull over and get back into traffic.
I would plan on making it as far as you can, but check on campgrounds or stops earlier so you aren't scrambling if you can't get as far south as you want. New Years Day, traffic shouldn't be bad early in the morning.
