Recommendations please for a car service to take from CDG to Paris hotel for 6-7 people.

Here is a link you might find helpful-it shows where the locations for the taxi stands are at each terminal:

Taxi fares

A flat rate is applied for taxi journey from the capital to Paris airports and vice versa.
Between Paris-Charles de Gaulle airport and Paris "right bank": €50
Between Paris-Charles de Gaulle airport and Paris "left bank": €55


Just be aware you will probably have people approach you as you get out of arrivals trying to get you to use their services. Just move on to the official taxi stand. The line moves quickly and as geetika said they will have someone there who can wave over a larger vehicle. I do believe there is a 4 euro supplement charged for an additional passengers over 4 people.

Thank you so much! These fixed rates are definitely cheaper than the car services I saw online.

It is a fixed price to go back to the airport from Marriott on the Champs Elysees?

There is a 4 euro supplement per passenger starting with the 5th passenger.

Yes according to my reading it is fixed price either direction. I have actually only gone from CDG to the city since I mostly leave France from some other city.

I second (third, fourth) travel to Paris by taxi. And for the trip back to the airport, I strongly suggest downloading the G7 Taxi app which allows you to order a taxi online. Très facile!
