It is my first time using eurail. I will be traveling with my wife and three children: 2, 4, and 6 years old.
I will be traveling from Paris to Biarritz. I want to take the fast train that takes about four hours. Can somebody tell me how much the additional charge will be to book this trip when I make the reservation?
Also, what happens if I miss my train for some reason. Can I use the ticket for the same trip the following day or something like that?
Thanks so much!
