If you go on a Euro trip there's really no need to pay for an organised tour, it's pretty easy to plan it and drive it all yourself. Just look online and there are plenty of well known routes you can take. Either buy a set of European maps for a satnav or just go old sdchool and buy a road atlas. To be honest the only confusing thing you'll come across is trying to navigate through the Belgian ringroad network. @EF Ian, other people crashing is quite a concern, when I last went I saw at least 6 cars get written off!
