Not all at once, we were thinking of stopping somewhere in France for 4 nights, then doing a second long drive into Italy, stopping there for another 4 nights, then a third 4 night stop halfway home. Each leg of the journey would be about 12 hours, which we were thinking of doing overnight so the kids sleep through it.
There would be two of us sharing the driving, and I usually work nights, so I'm confident about my ability to stay up and still be alert. Would this work or would we just be tired and crabby for half the holiday and loose too much time sleeping before/ after each drive?
