Sorry if this has been discussed but only posting I found were pretty old.
Next month we will be arriving at cdg 2G on Air France from vienna after 10 days in Germany and Austria. We want get to the Rer B station. I assume we collect luggage downstairs in 2G, then it's a little fuzzy. I think we take the N2 shuttle bus to 2E and then meander to the train station or maybe then get on N1 to get a little closer to the train station. Is there really not something more like a tram to do this connection?
Also, is there any security/immigration since we are arriving after a week in Austria.
Thx...
