I'm sure this topic has been covered but I did the advance google search for it and didn't find anything too relevant.
Is it better to book online for point-to-point train tickets or wait until I get to France? I have found fares and times on tgv.com and gotten a total of $322 for Paris to Arles, Arles to Nice, and Nice to Milan. I don't know if this is a good deal?? This price is for 2 people under 26.
I know I have to make reservations for some trains, but couldn't I do this a few days before?
