Hi, we are (2adults/2children) coming to Paris at Saturday and we will stay till Thursday. What is the best way or what ticket to buy to visit Paris?
For Saturday getting into the city, buy single RER tickets from CDG to Paris to get yourselves to your hotel. If you need further transportation that day, share a carnet of Ticket t+. For Sunday if you plan on at least 4 rides on Metro or bus, buy a ticket Mobilis 1-3 zone day pass for two adults and buy two Tickets Jeunes Weekend 1-3 zone for the two children. For Monday till Thursday, get the Navigo pass for everyone. This will be useful to get back to the airports as well.
