Hi, I am planning a trip in Swiss Alps, starting in Bern (one hight), 3 nights in Crans-Montana (visiting Zermatt area and around), pick up the Glacier Express, down in Disentis (fithth night), continuing to St Moritz and spend a day there. After that I think in stay at night in Filisur or Thusis (or even in St Moritz it will be possible $$) and return to Zurich at the same day.
So, in a short way:
1st day - Bern
2nd day - Bern - Crans-montana
3th day - Crans-montana
4th day - Crans-montana- Zermatt
5th day - Crans-montana - Glacier Express - Disentis
6th day - Disentis - St Moritz (Filisur or Thusis)
7th day - (St Moritz or Filisur or Thusis) - Zurich
Is this a possible itinerary? Are you see any fault, including time schedules?
