I need to get from RER B to Disneyland - probably will be coming from Saint Remy les Chevreuse. It looks like this is fairly straightforward transfer at Chatelet to RER A to Disneyland. Is there a more direct route on another train?Since I have to travel 5 zones in and the 5 zones back out, is a 5 zone ticket sufficient for this trip? Thanks
RER B to RER A transferring at Châtelet is the most direct route to get to Disneyland Paris coming from south of Paris.
For this trip you would purchase a RER train station to station ticket, known as a billet origin-destination, priced from the departing station to the arrival station. Which in this case would be a zone 5 to zone 1, then zone 1 to zone 5 priced ticket, which is €12.10 for St-Remy-lès-Chevreuse to Marne La Vallee station.
