Good morning, I'm going next March 20, Wednesday to Paris.
I will be staying with some relatives in Thiais, whose nearest station is Gare Choisy le Roy. As I will stay for a week, I will need to go to the Center of Paris every day (go back in the morning and come back at night), in addition to the whole center of Paris, I also want to visit Versailles and Disney, but my biggest In my case, what would be the best option for greater savings, between individual passes or tickets, given that I need to ride RER, Metro and possibly Bus? Thank you in advance for your future assistance and attention.
The best pass to buy is the Navigo Decouverte week pass. You'll need to buy one on Wednesday when you arrive and recharge it anytime between Friday and Sunday so that it will work from Monday-Wednesday during the following week. Navigo will work on Metro, RER, Bus and Transilien trains.
Navigo Decouverte week pass will be still the cheapest & best option for you to travel between Choisy Le Roi and Paris each day.
