bonjour.
you paid for your metro tickets during your tour? I am so sorry. Of course that cost is on us.
Not sure what happened here. I will be in touch with you directly to sort out.
And yes, this private tour includes public transport costs like metro and the bus (not a private car or a taxi, that would be different. but metro, yes, of course).
also fyi, our "Paris with kids" service includes a guide that specializes in kids, with dedicated training. We also adjust the route and content according to the age and the interests of the kids on the tour.
thank you, and happy travels,
