I have read the pages on rail europe and am still unsure. I only need to reserve a train if it is high speed. I am only traveling in france switzerland and italy so I believe the only one is TGV.
I need to know if I need to reserver for the following trips
from paris to Bern YES
Bern to Geneva NO?
Geneva to nice Yes
nice to Monterosso No
Monterosso to milan No
Any help would be great. Thanks
