I had a good laugh at the comment about relying on the folks at the AF Bus desk at CDG late at night speaking English-That's really a good one!

Two women with luggage, unfamiliar with Paris, arriving at CDG at 10pm should take a cab. Have your hotel's name, street address and phone number on a piece of paper to hand the cab driver-a page from the hotel website would be even better. I agree that the fare estimate of 50 Euros is about right, though you might do a little better than that late at night.

The problem with the AF buses (and there are 4, not 3-see info here: http://www.airfrance.com/double6/pas...F?OpenDocument

is that they do not go near enough to your hotel to walk. You would have to take a cab or the Metro. The Metro wouldn't be very handy with luggage and the best routing (Bus 2 to the Arc, then the #1 Metro to the Louvre) is likely to result in a packed Metro car at that hour. Also the savings are small since the AF bus is around 12 E one way per person.

The Roissybus is cheaper than the AF buses, but has the same negatives, plus there's no separate luggage area so you have to lug your bags onto the bus with you.

Then there are those airport shuttles, and when I think of them, I think of motorcycles. Why? Because it seems all the motorcycle stories end with "The Crach", and all the airport shuttle stories end with "The time they didn't show up and I waited an hour and a half for them".

As for the RER, I don't take the RER after around 7pm even within Paris, and taking it from CDG through those scary, tough neighborhoods at night is just a needless risk. I know folks will say "I take it all the time and no problem" but I would not suggest it.
