I read that the Ticket mobilis gives unlimited metro rides (excluding RER) for one day.
How do you count the day?
Is it per operational day (opening to closing of metro) or per 24 hours from stamping of ticket (e.g. 9:30pm today until 9:30p.m. tomorrow)
By the way, if you change from one line to another, do you have to buy another set of tickets?
For example, I would like to go from Blance, Montamartre to Eiffel tower. I take Line 2, change at C. de Gaulle Etoile, take Line 6 until Bir Hakeim. Does this ride require 2 tickets?
We are arriving at past 8pm and will ride the metro multiple times the following day. Im thinking of buying Ticket Mobilis for first day and use carnet for the following days.
