My husband and I have 4 kids (at the time age 18mo-9yr), and this past summer we went on vacation to Gatlinburg, TN--an 8 hour drive. We have a DVD player in the car, and they all got to choose 1 or 2 movies to take with us. I also packed a backpack for all of them with new (cheap) toys, travel games, and their favorite snacks. We also played the I spy game and tracked how many different license plates we saw and whether they were on semi's or private vehicles. On the way home, we re-arranged their backpacks and swapped toys and games. It was the best trip with kids! We also had travel pillows for them to rest their heads on when they were sleepy.
