I am planning to travel Europe on a budget and having bought some budget flights, I am left with some sectors which don't have connecting cheap flights and day trains are too time wasting. I wish to take the night train and and since I am on a budget and also cannot sleep in anything moving, can I just pay for the seat without paying extra for any sleeper ?
I am thinking of:
Somewhere in Switzerland(to be decided later) to La Spezia or Venice and Venice to Naples or Rome.
Thanks alot.
