Greetings- I am excited to be back in Paris this fall. In going thru my file from my 2018 visite, I found my Navigo Decouverte pass (with photo) in its plastic holder. I think there may even be a few Euros left. It was last used July 2018 (Fun watching the Tour de France final day spectacle!). I cannot tell from the official websites if it would still be valid. Wondering if anyone else has experience using an older pass or am I likely to need a new one? We are staying Monday thru Sunday so the weekly pass is perfect.
Merci! Kat
