Hello, I’m a tourist. I will travel for 1 day. I will get on from Bern and get off at the stops in Thun, Brienz and Luzern and visit those places. Then I will continue to Zurich. If I buy a “Saver Day Pass” ticket, do I need to pay additional ticket fees to go to these stops? So when I buy a “Saver Day Pass” ticket, can I travel by train unlimitedly and free of charge for one day? Thank you in advance
(Note: i have no “half fare travel” card.
