I should like to book a return trip between CDG Airport and Marne la Vallée Chessy out on 29-NOV-15 and back on 02-DMR-15. Voyages-SNCF steadfastly refuses to sell me tickets or even show train times. I can price it up on B-Europe but it requires me to collect the tickets in person from a Belgian or Dutch station, which I am not in a position to do. Does anyone know of any other sites or methods to get these tickets?
