Looking for a private ride shuttle service for two adults from CDG to Gare St Lazare, in order to take the train. Suggestions?
Did you not ask this same question a couple of days ago? In any case, take a taxi, not a shuttle, which is what everyone suggested on your other post.
Here is your other thread in case you missed the answers there: https://community.ricksteves.com/travel-forum/france/shuttle-service-from-cdg-airport-to-gare-st-lazare-train-station
