Heading to Ancona monday from Calais. I will be travelling after 8-10pm untill I hit my 500 mile mark. Thing is the toll route takes 20hours and covers 1313 miles, the none toll route takes 27 hours and covers 1359 miles. I am baffled at the time difference, any ideas folks? I'm thinking and aditional 7 hours drivong a 3 ltr motorhome could run into a lot of money. But the mile difference is staggering.... Help!!
