hello good morning,
I want to travel with my family from Grindelwald-Interlaken-Spiez-Brig-Oberwald-Gletsch-Realp-Andermatt-Chur.
The part Oberwald-Gletsch-Realp, I want to do it by bus to enjoy the views. My question is, if I travel using the Swiss Travel Pass I do not have to buy any ticket, so how can be sure that I will have a seat in these buses (B161 and B681) which cover Oberwald-Gletsch and Gletsch-Realp. Maybe what I am trying to do is impossible…
thank you
