the 5 zone Paris Visite is an overpriced tourist product which is almost never a good choice; it does cover the airport. The metro pass in the so called 'Paris Pass' is just a 3 zone Visite which is not good for the airport. If your dates fall between Mon and Sun of one week or more or less do so, then get a Navigo Decouverte which is good for all five zones, includes the airport and is 27 Euro including a one time charge of 5 Euro for the pass (you can recharge it for your next trip) If that is not going to work for your dates, buy a single ticket from the airport to Paris for 10 Euro and a two single tickets for Versailles (to and from) and for around Paris get a carnet of ordinary metro bus tickets to share with your companions. (10 tickets for 14.50.)
The Paris Pass is not a pass; it is a collection of other stuff you can buy if you want it for less. The museum access part of this kit, is an ordinary Museum Pass which is probably a good deal; just buy a Museum Pass when you get to Paris at the airport or the first museum you visit (pick one with short lines like the Conciergerie or the Cluny). It does give access to shorter security lines at most museums. The metro access is a Paris Visite which is almost never a good deal.
