Besides the car there are other ways to visit the area, the bus 500 stops at the bottom of the road and is a direct connection between Nice Airport and Grasse center, handy if you expect extra guests. The train from Grasse, via Mouans Sartoux to Cannes Nice etc. is highly recommended if you want to see a beautiful route along the coast to the Italian border Ventimiglia. You can get in and out of any train station, for example to have lunch on the coast. There is a ferry from Cannes to the islands off the coast, well worth a day trip.
