Travel passes, museum passes, combination passes. I'm confused. I'll be in Paris arriving on CDG for 6 days. What's the most economical? Get 3 day passes for transport to and from CDG and Versailles zone 1-5 and 1 week pass from Navigo weekly pass 1 - 3, Paris Museum Pass, Paris Visiter pass? Please help!
If you arrive at CDG from Monday to Thursday, get a Navigo week pass. It's the best/cheapest option. If you arrive Friday-Sunday, the Navigo pass isn't available/doesn't start working until Monday. If this is the case you need to decide what Paris transit pass works best for you based on where you want to go and for how many days.
