Some travel website mentioned about "seat reservation" and "validate ticket before boarding", can you help to explain on this? Does all train/coach need ticket validation and seat reservation?
When train ticket involve one country to another country, does the ticket valid for 1 month? If so, the 1 month validity ticket can be purchased online? Or only can be purchased at ticket counter? When the ticket start to take effect for 1 month validity? From the date of purchase?
Is that only can be purchased at Germany ticket counter? Can it be purchased online?
Do you think I should purchase Swiss pass?
For Bavaria (Fussen)->Basel : does Quer-durchs-Land-Ticket cover the route? Or I still need to purchase additional ticket?
For Italy regional train, do you know where I can get the timetable and fare?
You mentioned that I don't have buy regional train ticket in advance. Does this mean that I can definitely get the ticket even before departure?
For Paris local train including RER train, do i have to purchase in advance?
For Eurolines promo fare, i also have to purchase in advance?
To get around Swiss (e.g. Zurich -> Lucerne -> Berne -> Geneva ), can I buy international ticket at Italy instead of Germany? Will the tariff still be the same? Is purchase in advance needed for international ticket?
For International ticket, does the single ticket need to involve 2 different countries?
If I buy half-fare card online (I am not sure if I will be given card serial # though), will I able to get additonal 50% discount on top of the super saver ticket?
