Thanks for your helpful replies everytime.
Since I am still on research mode and my swiss travel plan is always evolving. The only thing I am done with till now is flight booking and accomodation.
Initially I was considering the 8 day swiss pass but after coming across those amazing scenic trails from Grindelwald or Wengen I am having second thoughts. I think a 4 day Bernese Oberland pass along with a half price card serves me better. So just sharing the revised itinerary and expecting some pro tips from you folks.
Reach Basel at 9 from Amsterdam then head off to Lucerne. (Half Price card)
Check in and they go for Mt. Rigi excursion based on the weather if not roam locally(Half Price card)
Go for Mt.Titlis Excusion (Half price card same benefit from Engelberg I believe)
Visit Titlis nad while coming back stop at Trübsee for exploring.
Early morning we start for Lauterbrunnen from Lucerne via Interlaken Ost (Bernese Oberland Pass.. no reservation required)
Check in at Lauterbrunnen then after taking a bit rest start off for Wengen around 1 pm..
From Wengen - Männlichen cable car then follow the trail to Kleine Scheidegg. (With Bernese oberland pass everything free).. While coming back from Kleine Scheidegg to Wengen/Lauterbrunnen what should we do walk back back to Wngen then catch train or other alternatives are there
Start for Grindelwald early. Then catch cablecar to First and hike to the Bachsee (All free with Bernese Oberland pass)
Then in the late afternoon catch train to Interlaken Ost and take a boat ride across Thun and visit Spiez. Then back to Lauterbrunnen. (All transportation covered with BOP)
From Lauterbrunnen cross the street (or use the underground walk) to the cable car to Grütschalp.
Then follow the trail to Mürren begining at the Grütschalp station where I depart the cable car. (Free with BOP)
I can catch the gondola up to the Schilthorn. Alternatively, if the weather looks like it is coming in during the afternoon, do this trip differently.
Take the cable car from Lauterbrunnen up to Grutschalp, the train from Grutscahlp to Murren, walk 15 mins through town to the cable carand head straight up to Schilthorn then take the gondola back to Murren.
From Murren then return down to Stechelberg ,
visit to the Trummelbach falls and walk along the lovely Lauterbrunnen valley back to Lauterbrunnen. (Trummelbach falls covered with BOP or Swiss pass?)
Lauterbrunnen to Bern: Reach Bern around 11 check -in luggage in station and go out for a city tour. If possible visit Gurten (Cable car free with BOP ????)
come back around 4 and take train to Geneva to catch the flight back to Amsterdam at 9pm. (Train is free with BOP and requires no reservation along the entire route)
I do not think there will be any further changes to the above itinerary. Please correct me if any of the above stated details are incorrect.
So the disadvantage I see with Half price card is the Rigi Excursion will not be free and the train to Engelberg for mt.Titlis.
The disadvantage with Swiss travell pass will be the cable cars to First from Grindelwald will not be free and the one from Murren to Männlichen .
I hope I am not missing out on any thing.
