This spring the taxi fare was about $40.00 to our hotel on the left bank--it should be about the same to the Marriott. I would suggest calling the Marriott concierge and asking about their rates for a car service to meet you in baggage claim. I was surprised to learn that our hotel (not as deluxe as Marriott) offered this service for about the same price (perhaps, $5.00-$10.00 more.).So, we used their car service for our return trip to CDG and it was very convenient. Not a limo, just a comfortable mini-van. . We had two large bags and were pleased to have had this service available.
