Not a tour...
There is a group of 4 to 5 couples that we have been renting villas with in Italy and France for the past 10 years.
Each trip, Rich & I try to add a bit on the front and back of the week and head in different directions.
This trip, the whole group decided to add a couple of days at the end in Paris, so our pre-villa time was our own.
I had seen an article in the Boston newspaper travel section about the Franche-Comte region and we used that as our guide.
As long as we are allowed to drive in Europe (at age 75 or so, renting a car there becomes impossible) and have the nerve to do it, we'll probably eschew tours.
