We are also in VA- SW Virginia and we have only driven once (and hopefully never again!) We have 3 kiddos and it was a LONG trip for everyone involved. It took us at least 12 hours to drive it and we split it up into 2 days. We borrowed a small tv for the van and watched movies and tried to play car games. I printed up a bunch of games and coloring sheets (disney) from the internet to try and keep the kids happy. Also packed snacks and drinks and when we stopped for fast food, we always had the kids play in the play area to run off some energy while DH and I ate and then got their kids meals to go and they ate in the car. Driving is definately not for us in long distance travels. We will stick with flying, but your DD may be perfectly happy for the ride- especially since there are no siblings to argue with!
