I read the France book but am still confused. When trying to get tickets on Capitaine Train site it is showing three different combos. First is SNCF with TER and TGV train numbers (connection). Second is IDTGV (no connection) and third is OUGO train but it looks like that one goes on to Marne-la Vallee (Disneyland). So I understand OUGO is not my choice.
A. My question is there a difference between SNCF and IDTGV? I see there is first and second class choices on both. Is one the super fast train? Is it worth is?
If TGV do I want upstairs or downstairs to see better?
Thanks.
