Hello from Wisconsin,
I checked minutes ago for a 2-week mini car rental without CDW insurance. Why a mini? Have you driven the back roads and into the old cities and villages of France? Well, I have. Want to blend in? They don't much drive Buick Le Sabres and other road hogs in France. Why rent without Collision Damage Waiver (insurance)? Why pay $15 to $20 per day when a credit card will offer the same thing, free. I use a credit card that will offer CDW free of charge if I make the rental online and then use the same card when collecting the car at the rental desk while declining insurance from the rental agency.
A few days ago the best price was near $300. Today it was $176. That is more like normal. Currently that rate is only available from the Paris Le Defense office with a return to CDG.
This is good news for self guided tourists.
