Hello Nujiha64
Good day …
We are unable to say that because we would need a detailed program. For such a short period, I would opt for the Saver Day Passes and Children Day Passes. They are not valid on most mountain excurses, however, except for Mt. Rigi, Mt. Stanserhorn, Klewenalp.
Not sure why you have chosen Zurich as a base while you want to see the Alps. This decision makes your stay more complicated and unnecessary expensive. Most tourists choose Zurich as their base as they think, the most known Swiss city must the the perfect base while Bern or Lucerne would be more suitable for someone who wants visiting the Alps. Zurich is not close to the Alps and will require you to commute there. It is a banking city where food is expensive just because it is ‘Zurich’.
With only two days to spare, you should not spend most of your days on trains … And with children, you should do a program that suits the children as well, for example a trip including tobogganing.
Lucerne offers steam paddle boats, a great experience for children as well.
Make a plan and come back to discuss it further.
Kind regards,
Roland
