paris/loire/burg

We will be flying into CDG and immediately driving down to Loire (3nts), Burgundy (3nts), and back up to Paris (3nts).

We don't want the rental car when we are in paris the last 3 nights.

How/where should we go about renting a car?

Should we rent it out of the airport? I'm just nervous about trying to find our way out!

If so, we'll have to return it to the airport when we arrive in Paris and then take a taxi/metro to our hotel.

 I have everything else booked but the car, but I'm not quite sure if there are other options for rental places outside of the airport, or if we could possibly have it picked up at our Paris hotel when we arrive.

 any advice or recommednation is appreciated.
