Sorry to bring up this question again...
Making a trip to Paris this weekend (arriving Friday ca. 1800 at CDG).
Staying at the Holiday Inn - Paris Montparnasse (10 Rue Gager-Gabillot Paris 75015). According to mappy.com it is only a 20 minute walk from the Gare Montparnasse where the Air France bus stops (can also take the metro from there of course).
The other option is the RER to Chatelet-Les Halles then a couple of metros (4 & 12) to Volontaires.
I'm leaning towards the bus at the moment, but will that be a lot slower than the other option that time of day?
All suggestions welcome.
Merci!
