Taxi to Aix-en-Provence
I know you mention private mini bus hire but do the taxis at the taxi rank also drive to Aix-en-Provence? If so how much do they charge?
I can't see why a taxi wouldn't take you to Aix-en-Provence and if they couldn't I'm sure they could call someone who could. The cost is about 135€. That's at 1.46€ per km for 92km, the cost per km for a taxi in the Gard department and the distance from the Nimes Airport to Aix-en-Provence.
