Question about traveling from CdG to Chartes on a Friday (3/24).
We're wondering if we can just get to Gare Montparnasse by local transit, and buy a ticket for the next SNCF direct-no-transfer train to Chartres.
I'm torn between the advice to always buy train tix in advance, and my sense that we have no idea how long it'll take to get from the airport to the Gare M. Do those SNCF trains to Chartres sell out?
I seem to have purchased an expensive, non-refundable, indirect pair of tickets to Chartres via Le Mans, but I guess it's a learning experience. AFOG!
