I was originally going to purchase the passe navigo decouverte Semaine for zones 1-4 for our 6 day stay in Paris (Tues-Mon).
However, we will be making two trips out of zone 4, one to visit friends in "Plaisir Grignon" in zone 5, and a day trip to "Livry Sur Seine" in zone 6 (near Melun). I was just going to purchase separate tickets for those two trips, but in researching costs, I am now thinking that the passe navigo decouverte semaine for zones 1-6 will be more economical. I have researched the RATP site and looked at the map for the transportation zones. Both are served by "reseau transilien", not the regular RER lines. I just wanted to verify that the passe navigo decouverte semaine (Zones 1-6) would cover those 2 trips. I am assuming since they are on the "Zones Tarifaires D'Ile-de-France RER and Transilien". Can anyone help me with this?
