Robespierre, the differenct in taking the Eurostar London-Paris and the RER into Paris from CDG is that there can be a LOT of stairs involved with the RER, not fun with luggage.

Obviously, I meant "difference."

If I recall correctly, there are multiple escalators (and a few elevators) at both ends of the trip.

Negotiating stairs is a non-issue.

Didn't mean the RER was bad just letting firsttime know that there are other options. My first 1/2 dozen times in Paris I stayed near the Opera so the Roissy bus was worth it. When I stayed in the Montparnasse area the Air France stop was about 100 yards from my hotel.
(p.s.- Robespierre, your back would get it if you had to haul around luggage for two people--being a nice daughter-- up and down those metro stairs when you have to change trains. God forbid it be at Les Halles when you have to walk across Paris to get to the next metro.)

Robes-You may recall correctly at the Metro stops you used but not all of them have escalators and or elevators. And yes I will use the RER again from CDG if that is the best way to where I am staying.

My remarks are mainly addressed to those who feel that a bus is somehow "easier" than than the RER to get from the airport to town. Since all the major RER stops have escalators to the surface, it really isn't all that rigorous.

Whether you arrive at Op&eacute;ra on the Roissybus, Gare de Lyon on the Air France bus, or Luxembourg on the RER (for examples), you <i>still</i> have to get from there to your destination, and the amount of effort it takes is more or less constant, be it by walking, taxi, M&eacute;tro, or RATP bus.

If you choose one mode over the other because of its proximity to your destination, I would concur. But all other factors being equal, there is no difference between the train and buses (except the RER is cheaper and faster).
