Thanks for the tips! I'll definately let my husband take the wheel through those areas. At least when we're finally in Anaheim we can park and walk across to Disneyland and get a break from LA driving for a few days. Universal is definately on the to-do list as is the walk of stars, still not sure about knotts.
Our girls are 12 and 15 now so not little kids that will whine and squirm the whole way there which makes longer days more possible. 12 yr old wants to do the scenic route and make the holiday seem like it's lasting forever, 15 yr old just wants Mickey. Of course they can't agree!
I think we will drive as long and hard as we can the first day. Take two hotel night stays on the way down, with one being somewhere along the coast there, and try to make it into LA after 7pm the third day. Too fast to take in any attractions but there will be a nice view on the way down and time to stop for photos and meals that don't come from a drivethru window.
Maybe I can talk hubby into taking another road trip next year to see parts of the Oregon coast and the Redwoods :D
