Thanks All for your help !
I am going from May 4th (arriving Geneva at 12 noon) and leaving from Zurich on May 13th.
@rockoyster Thanks for your tip about using the regular bus/train / boat route, and the routes :) really helps a lot !
@lukas - the links you sent are very informative, think I'll buy the consecutive day pass as you advised as it adds far more flexibility. Cheers !
Just creating my final itenerary for the trip.Summarizing, it stands as this. Let me know what you think and is it a bit too ambitious/ any places that should be substituted, removed or added. Only the stays for the night are fixed, hence can't add a stay for the night anywhere.
May 4: arrival Geneva (2 hrs - see the Jet D'Eau.)Travel to Montreaux ( Chateau D'Chillon as a stop) and then onwards to Grindelwald by regular train ( think this covers the golden panorama route )
May 5: Grindelwald hiking, seeing "First" , glacier canyon walk.
May 6: Schilthorn, also stop at Lauterbrunnen and Murren. ( Think all rides from Grindelwald to these places including cable car are free with the swiss pass)
May 7: Zermatt ?? Is this worth it after seeing Schilthorn. Have seen Kitzsteinhorn in Austria so was thinking Junfraujoch might be similar ?
Else will do hiking in Grindelwald on that day.
May 8: nothing planned
May 9 - go to Engelberg via some time spent in Interlaken/Lucerne.
May 10: was thinking of one of the scenic routes, although will have to let go of this idea as it is too tight a schedule to return back to Engelberg for the night. :(
May 11: Engelberg to Lugano. Spend the day in Lugano. / Half day in Lugano : Half day in Luzern.
May 12: nothing planned as such.
May 13: Engelberg to Zurich, see the Rhine falls (2-3 hrs), public transport to get a feel of Zurich and fly back at 9:45 pm.
Thanks again for reading my lengthy posts, really appreciate the same :)
