Hello everyone. I'm watching videos and reading up on how the Metro works in Paris and I think I mostly understand it, but I'd like to clarify a few things so we're not stopped by security. We'll be traveling with 2 adults and 3 kids aged 11, 8 and 6. I understand that the 2 adults and 11 year old will need their own separate adult tickets, and the 8 and 6 year old will receive discount child fares, but still need their own individual tickets.
We'll also be in London prior to Paris, and whereas in London my husband and I just scan our own tickets (on the contactless pay on our phones) and the kids can walk through the turnstiles with us (tube is free for under 11 yes?), this is not the case in Paris, correct?
I've downloaded the IDF Mobilities app, but if all 5 of us need our own individual ticket, I can't use the app for my kids, is that right? We will be in Paris from a Tuesday - Monday so is the Navigo Easy card the best option (over the weekly pass)? And if we buy the 10 pack of tickets, do those carry over from one day to the next or do they all have the used in the same day? My plan is to have one adult tap through, then the 3 kids, then the second adult, so the kids aren't alone on either side at any time.
ETA: We won't need transport to the airport in either direction and the one day trip we will be doing with be Versailles, all other travels will remain inside the Paris 'circle' if that's the correct terminology.
I feel like I finally understand the tube and now I want to understand the Metro too. Thanks!
