Is it possible to buy one ticket to cover a rail trip from Berlin to Prague over 5 or 6 days. We would like to stop overnight at Leipzig, Dresden?
Unfortunately, an international one way ticket is only valid for two days. In addition, the journey via Leipzig is a detour that you have to book separately. If your route will be really Leipzig (overnight) - Drseden (overnight) - Prague, it is easier to book separate tickets for each leg. You should book the last segment, i.e. Dresden - Prague, with Czech Railways (www.cd.cz), as it is usually much cheaper there than with DB.
