Hi,
I'm planning a trip to Paris and would like to get more info about taking the trains. My destination will be Versailles-Rive Droite station. From CDG airport, I need to take the RER B line to Chatelet le Halles station, then transfer to the RER A line to La Defense station, then connect to the L line to Versailles-Rive Droite station.
When transferring between all of the RER lines and the L line, do I need to get an additional fare ticket or the single ticket that will be purchased at CDG will cover this entire route (one way)?
Thanks.
