Hello Carlos MC
We cannot provide help in Spanish.
With a point-to-point ticket you can take as many stops as you want along the route, and continue later. No backtracking is possible, and the trip has to be completed until 5 a.m. the next day. Same is possible with a Saver Day Pass.
Supersaver tickets do not allow stops along the route unless you split them into to trips Zurich - Bern / Bern - Zermatt. It is not recommended to use Supersaver tickets when arriving to Switzerland by air.
Kind regards,
Roland
