Beat the jams
It's not the most laid-back drivers who are the most relaxed when they arrive at their destination - it's the best prepared.
So, plan your route, find out what roadworks are happening and, if necessary, work out a way round them.
To keep yourself fresh, plan stops at roughly two-hour or 100-mile intervals, and not necessarily at service stations. Consider leaving the main routes to find a more relaxing pub or caf.
And, to cope with any unexpected delay, take toys and games for your children, and music for yourself, and make sure you've got plenty of water and snacks.
It pays to do your homework before you leave, so use the information below:
