I was fortunate enough to spend several days in Paris recently,  this was before all the disturbances began.  This was not my first trip there and I felt reasonably comfortable trying to navigate leaving the airport and buying tickets for the subway system.  A helpful gentleman working at the airport directed me to another type of ticket.  This was good for 1 week and valid on subway, buses and trains throughout Paris.  Would reasonably get me from the airport to our hotel and everywhere we wanted to tour.

So we happily purchased the tickets and proceeded to board the next train bound for the city center towards our hotel.  About halfway there the train stopped and they announced something in French which I could not understand.  Then required all of the passengers to disembark.  That train left with a number of announcements happening.  Another train sitting on the next track…
