We also managed to catch the earlier ferry making the final leg a little bit easier. In the end it was a 14.5 hour drive from Florence to Calais.
An extra turn of speed through Belgium (the best way to head South from Calais I think) meant that our 20 litres of fuel added with 509km to go was only just enough to reach the port. For the last 30km I had to drop the speed to save fuel. We now have about 3 miles of petrol left to make it to a filling station in Dover.
You'll be glad to know Phil's got his car booked in for Friday morning to get the aircon sorted. In the end it wasn't too much of a problem for us, the windows still worked after all.
We'll now switch back to BST, mph and the right side of the road. We're not expecting any problems for the last leg of our journey, again, all fingers crossed.
