1. I know that the Navigo Découverte lasts for 10 years, but what if there is an extended period of inactivity on it (4 or 5 years)? Does it have to be reactivated? Or does it just work automatically the next time the Navigo semaine is loaded on it?
2. When we arrive at CDG, it will be too soon to buy the next week's Navigo semaine (we arrive on Thurs.), but since we will have a lot of time until our TGV train leaves, I thought I would purchase the Navigo Découverte for my son so that it will be ready to load with the Navigo semaine a couple of days later. He has an old one, but he looked a lot younger when I first bought it for him, and I know he'll want a new one (avec beard). Should I ask:
'Je voudrais acheter seulement un Navigo Découverte svp, pas un Navigo semaine."
My concern is that when I ask for a Navigo Découverte, they will think that I'm also trying to buy the weekly pass (which is not available for sale yet), and they will tell me that I can't buy it.
