I am trying to cost up the price of fuel for a journey driving from dublin ireland to Lazise on lake Garda. The pricing of the journey would really start from holyhead in uk to dover in uk and Then driving from dunkirk in France Down to lake Garda in Italy via belgium, luxembourg and switzerland. We are driving a BMW 5 series diesel. We are planning on doing this trip in July next year but I'm afraid the cost of the fuel is going to make this into a very expensive trip. Has anyone any costings for this please.
