I will be taking a tgv train from Avignon to Charles de Gaulle, and then spending 1 night at Citizen M hotel. Which station should I plan to arrive in?
You will arrive at the TGV station at Terminal 2 at CDG. If there are no trains to the airport from Avignon when you wish to travel, you can go Gare de Lyon in Paris.
Thanks, but is that closer to the hotel than taking the train to the airport 1 station?
You don't have a choice of stations if you are taking the TGV. The TGV stops only at the station at Terminal 2. There are indeed two stations at CDG but one is serviced only by the RER B train which is the commuter train that connects CDG to Paris. Now, if you take the TGV to Gare de Lyon and take the RER B line from Paris to CDG, you would exit the train at the Aeroport Charles de Gaulle 1 stop to be closer to your hotel. And if you do take the TGV to CDG, there is a light rail system (CDGVAL) that you can take to get from Terminal 2 to Terminal 3 Roissypole/Aeroport Charles de Gaulle 1.
Thanks for the help. Ticket to terminal 2 now made.
