Did this with my son in 2010. One of the best holidays we ever had. We hired a car and camped, mostly in what they called municipal camp sites. French hospitality was great. As a bonus we were there during the World Cup as well so got to watch some great football in French pubs.
As for the race, the GC winner was pretty much in the bag by the end of the first week. But otherwise, great riding from Ben O"Connor. And WVA winning a high mountain stage, an ITT and a sprint stage, that's out of this world.
