We are picking up a car in Avignon, driving around that area, through the Luberon, on through the Canyon de Verdon, ending up in Nice. I was going to purchase Michelin 527, but I see that it was published in 2007. Would it be better to get the 2014 Michelin Road Atlas? Or how about the Michelin 2014 Southern France? I am confused as to the difference between the various offerings on the Michelin site. Thanks.
