<span;>Hello, We will come from Turkey as 18 people. I have a few questions. 1) How can we benefit from group discounts on train tickets? 2) can we take advantage of the supersaver tickets? And what is its scope? 3) for example we bought a ticket from zurich to interlaken. Can we get off Luzern and take a train to Interlaken a few hours later using the same ticket? Thank you in advance for your help.
