We will be renting a car from the Avignon TGV station area. We are staying in ISLS. I am so nervous about driving around & getting lost. I am renting a gps. Not sure how to use one. I don't see many addresses to sights, so I don't know how much help the gps will be. I got a map. Will google map driving directions help, if I do that before I leave? I am so stressed about it. We will be taking day trips around. ANy help will be appreciated.
