Looking at variety of transportation options on our five day stay in Paris which begins on a Friday. Have ruled out Paris Visite and Navigo cards, but seems like for our “Fountainbleau Day” that a one day Mobilis Zone 1-5 One Day Pass is a good choice at €17.80 because a one way Billet Ticket from Gare de Lyon to Fountainbleau - Avon is € 8.85, or round trip for € 17.70. Since we plan to take another 3- 5 Metro, Bus and /or RER separate trips on the same day after arriving back in Central Paris, it seems we would be foolish not to buy the Mobilis 1-5 Day Pass for that day and save our carnet of T+ Tickets for the few trips in the city we will take on the other days, am I correct?
Also, I read somewhere that you can only buy an extended zone Mobilis Pass in the particular zone where you purchase it. In other words, that I cannot buy a zone 1-5 Mobilis Pass unless I am in zone
Is this true?
Finally, do you buy Mobilis Passes from the same ticket machines and ticket counters in stations where you buy T+ tickets and Billet Tickets?
