We will arrive in Paris next month on a Saturday and depart early on a Thursday morning, with a likely cab to Gare de Lyon on the day of departure, so really we will need tickets for Saturday through Wednesday. I've been playing with the different metro pass options and this is the most economical version I've managed to come up with. I think it makes sense but I'd like some feedback.
For myself and husband: carnet for Saturday and Sunday, Navigo Decouverte for Monday through Wednesday
For the two kids (under 9): tickets jeunes for Saturday and Sunday, kids' carnets for Monday through Wednesday, separate RER ticket for visit to Versailles
With one adult carnet and two kids', this would run a bit over 100 Euro, which I think is not bad for five days for four people. Any other ideas of combinations of the various options would be welcomed. Only ride outside zone 2-3 is likely to be on the Versailles visit.
