I have just priced up flights and car hire to Le Marche in Italy this summer and they come to £1000. I'm assuming even with diesel, we could drive there for a lot less money and use our own car on holiday (the property is not served by buses as it is up a mountain, so a car is a necessity).
However, we have children who will be 5 and 3 and the routefinder says it is a 19hour drive from our house.
Is it madness to even consider doing this?
