Oh you lucky, lucky thing!!! when I was married to ex we went to the Cannes Film Festival every year (working, not celeb gazing). we would then take a week to drive North throughout most of France, taking the byways and staying in chateau hotels which were reasonably priced then. It was wonderful, I loved every minute of it. we did this for about 12 years.
Now I live in SW France and we hardly every leave the valley! I still have to pinch myself that we actually live here (and have done for 16 years), the scenery is wonderful, far far less crowded than the UK and the roads are good, even the motorways are usually uncrowded, except the dreaded Autoroute du soleil down the East of the Massif Central, so avoid that, but there are many, many fabulous routes away from this.
We did recently go with friends for a few days in Brittany when lockdown allowed. still a wonderful trip.
Just go Granny go! take maps (nag nav takes the fun out of it), music, knitting, story CDs etc. Have a load of fun.
