Hello,
We are three travelers (aged 16, 26, and 28) planning a trip to Switzerland.
We will stay in Basel and want to go on one-day trips to Interlaken and the next day to Luzerne.
I want to ask what are the best and cheapest tickets option in our case. And can non-Swiss people purchase the super saver ticket, we are trying to book everything in advance as I see the prices increase daily?
