We drove from Saratoga NY to Fla when the kids were 4 and 6
and just be aware that not all kids SLEEP on the drive
we left at 6 am and drove to SC and the girls never closed there eyes once
i was shocked
we didn't have a car tv but brought lots of activites and the ride was ok
i learned a few things though
1.) be willing to make a few extra rest stops nicer ride when the kiddos are comfortable
2.) when packing the car to leave remember you WILL be coming home with more than you left with i did not plan for this and rode home with a bunch of suvioners under my feet NOT COMFORTABLE
3.) rent don't take your own we had transmission trouble on the way home if it had been a rental easy to call for a replacement as it was our car OUCH the repair bill hurt after just spending 7 days in fla
4.) when comparing rental car to air fare don't forget to factor in the additional coats of driving
gas
all the meals on the road
hotel ( if you are not driving straight through)
how tired the adults are when you finally get to WDW
all that being said we are considering driving again now that the kids are 10 and 8
we are waiting to see which is more cost effective
have a great trip no matter what you decide
