We are coming with 8 people to Paris ......who should we use from CDG to Paris for a private transfer ?? we will have teenagers and I don't want to deal with train,etc...

I would head out to the taxi stand and take two cabs to the hotel. Quick, easy, and stress free.

Ditto

how much would a taxi cost ?? we are staying at a Hotel near the Eiffel Tower

It should be around 50 € each, maybe a bit more with the luggage, 4th person, etc. supplements.

If you do some searching on this forum you'll get estimates. Usually, for 4 a taxi is the same or cheaper than a shuttle. I would guess a taxi to ET would be in the 45-50 Euro range. The highest I've seen recently is 65 when someone got stuck in traffic. To me, there's no comparison. I don't want to wait to start my trip and don't want to be frustrated by no-show shuttles and roundabout routes to my hotel. I take a taxi irregardless. But, with 4 you won't be paying more - and will have much more convenience.

we will have 8 total so we will need 2 taxi's...I DON'T want too get a transfer that makes multiple stops...I was thinking a private van for all 8 ?? But if 2 taxi's are the best then we will do that !!!

Be sure to take a "Taxi Parisien" and not a gypsy cab. Last visit one of these jokers offered me a fare of 100€! Have the address written down to show to the driver. You will be charged .90€ per piece of luggage and 2.60€ for the fourth passenger.

thank you very very much

4 of us took a cab from CDG to 5th arr. 3 weeks ago for 62€ (includes a small tip). We used "Airport Connection" on the way out of Paris for a trip to a farther away airport. They offer private vans. Go to their web site for prices. Airport-connection.com. There are several other companies that offer private shuttles also.
