Good afternoon, we are looking to arrive in orly airport. Take then train into paris to take in a few sights before train to disney later the same day. The orlval service from the airport to the station seems expensive as it covers train into disney centre as well. If we get billet mobilis tickets to cover us for the day it does not cover the srvice from the airport but we are edfectivly paying twice to get to paris centre. Is there any other cheaper option for our requiements? (Family of four )
With a Ticket Mobilis 1-4 zone you can go from Orly Airport to Paris using Orlybus or Tram 7, but not Orlyval train. (Orlyval train is owned/operated by a private company, not the Paris train authority.) But, since you are also going to Disneyland Paris, you will need a Paris Visite 1-5 zone, as Disney (Marne la Vallée station) is in zone 5.
This will be your cheapest option for day pases from Orly to Paris to Disney.
