This may be a silly question but I just want to clarify something:
If I am going for example from Rue du Longchamp (Metro Trocadero) to Notre Dame or any other tourist site and this requires a change of metro line, will this require more than one ticket or will one ticket do for the whole journey?
I'm trying to decide if we need four books (four of us going so one book each) for four days.
Havent used the metro system before so not sure.
Thanks for any info.
