My wife and I will be in Paris on first week of September, arriving at CDG airport on Monday at 6:40am. We will stay at Mercure Paris Centre Tour Eiffel for 7 nights and depart on Monday 12:00pm. During our stay we plan to move around using public transport in the Paris city center and we will also travel only once out of Paris to Versailles.
Should we buy the Navigo Découverte transportation Pass for a week?
Should we buy only Zone 1-2 and pay cash for the Versailles?
Or shall we buy Zone 1-4 for all our trips?
Read in TA that we can purchase the Navigo Découverte from ticket windows from a metro or RER station or local tabacs. Is there any local tabacs near our hotel that sell the Navigo Découverte?
My wife and I will carry a 20kg checkin baggage each when we arrive at CDG. Shall we buy the Navigo Découverte at the airport and use it straight away to go to our hotel (which will save us no less than 50€)? We also read about pick pocket etc etc in the Metro and so we don't mind spending 50€+ for the taxi from CDG to hotel but wonder if the traffic jam at that hour will be a problem? ( We won't want to get caught in a traffic jam in a taxi wasting time and money.)
