Okay, so I just bought a Z-Card, and I want to travel to about a billion placed in the Czech Republic. I have a bunch of questions about the trains, however: 1) Please confirm that tickets work like this: I buy a ticket from Prague to Benesov.. I can now use this ticket on any train, at any time, as much as I want as long as it's between Prague and Benesov (and all stops in between). 2) My ticket (if it's domestic) is valid for use at any time for two days. 3) How do I know which class I'm sitting in on the train? I know "Trida" means class, but when I go on the train I don't know if I've wondered into first class. Also, how is first class different? How much more is it? I'm going to have more questions about this whole train thing, but for now this is enough... Thanks everyone!!!
