Give me your best tips for long road trips with the kids. I haven't been driving that long, and our longest trip has been about three straight hours of driving, each way (maybe a little more on the return trip). This summer, we're going to be doing over 1,000 miles (round trip), camping along the way. We have 3-4 days to get where we're going, and 2-3 days to get back. We'll be spending the intervening time at a cabin with my in-laws. We're taking all four kids. So, we're going to have a very full van (clothes, etc. for six people, plus recreational items - books, games, art supplies, etc., and camping gear).
I'll probably try a couple books on CD. The kids will have their art supplies, and we'll have music. I'll probably throw in some of my car and truck tally sheets. But....any other suggestions?
