Hello. I’m a tourist, coming to the Switzerland for the first time in February for 2 days only. I’ve be travelling a bit from Zürich, to Rapperswil, to Lauterbrunnen and back to Zürich. I’m trying to understand how to buy the SBB tickets online, what price should I choose: a Point-to-Point ticket or a Saver Day Pass, because it’s chosen by default when I try to book a ticket?
