We are arriving by Eurostar on a Thursday night and departing from CDG on a Monday afternoon. I'm confused by the options. What is going to be the best purchase, since we will be going to Versailles on Sunday for the day?
Buy a Navigo Easy pass with 2 items on it:
- a "carnet" of 10 Metro tickets (like a virual discount booklet of 10 tickets)
- a Navigo Day Pass for Sunday
Buy this from a ticket window for Metro, or RER or Transilien from an agent who can help you do this.
Versailles on Sunday will be covered by the Day Pass which is by default 1-5 zones (Versailles is in zone 4).
