We finish our cruise in Barcelona in mid September and are joining friends in Vinsobrues (France) a few days later. We thought we'd drive up (4.5hours) and enjoy the sights on our way there. Do any experts have any advice on this? Barcelona traffic is described as a nightmare, but since we are leaving the city I presume it shouldn't be so much of a problem? We would hire a rental car so are there any additional problems with a one way hire, dropping off in a different country?
The only other alternative is presumably a train?
