I have read many of the threads about carnets, Visite Pass, Paris Pass, Decouverte, etc. & I understand the differences, yet I am still undecided for our 2 wk stay in June. My husband & I will be taking our 1st trip to Paris, staying in Le Marais, arriving CDG on a Saturday, leaving by train from Gare du Nord also on a Saturday. I'm considering a one-way single train ticket CDG to Bastille, then staying within walking distance (Notre Dame, Latin Quarter, Bvd St. Germain) on Sat & Sun until the Decouverte pass is active for the next week (Mon thru Sun). The one trip I am sure we will take outside of Zone 1-2 during our 2 wks will be Versailles.
My question is - if we get one week of Zone 1-5 & go to Versailles during that week, are there other destinations on the Metro in Zone 3-5 that anyone can recommend in order to make use of the larger travel area while we have it? We could then probably get the pass for just zone 1-2 for the other week. We are also willing to walk, so I wonder if (weather permitting) we might just do better with a couple of carnets & a Versailles round trip as needed instead of a pass?
I appreciate the sage advice from the experienced travelers on this site - thanks in advance!
