i have an old navigo decouverte card from 2016. can i still use it? or is there a way to exchange it for the new version?
i also have a question about which pass to use for two (but more like 1.5 days) in paris. i will be in paris wednesday to tuesday. i will get the weekly decouverte card on wednesday. but i am trying to decide what to do for monday and tuesday. monday i was hoping to go to fountainbleu and tuesday my flight departs ORY at 6am. is it worth to get a mobilis 1 day or just get carnet of T+ and pay for the ile de france ticket to/from fountainbleu? can i even load carnet t+ on the decouverte? i was also hoping to take the N22 bus from chatelet to ORY on tuesday early morning ~3am. the RATP site has the timetable for N22 but when i try to use the trip planner it does not give me the option. is the N22 running?
thank you for any advice!
You can use Navigo cards for 10 years from original purchase so yours from 2016 should still work until 2026.
For your day in Fontainebleau I would say just a pair of RER tickets would be best. It'll be 5€ each way making a Navigo Day pass 1-5 zone (20.10€) overkill (unless you're doing a bunch of other trips that day).
For Chatelet to Orly, yes the night bus N22 will be running and you'd need only a single, regular Ticket t+ for that ride.
Navigo Découverte cards can't store any single-use fares like Ticket t+ nor RER tickets, nor Orlybus/Roissybus. The Navigo Easy can store Ticket t+ tickets as well as Orlybus/Roissybus and Navigo Day passes, but still not RER tickets.
