It just isn't worth the cost and we got 50% discount with our Berner Oberland Regional travel passes. The views were nice, but just about everything else up there is tacky and/or touristy. The train ride is very nice until Kleine Scheidegg, but after that it is mostly in a tunnel. So save yourself a ton of money and just buy a regular train ticket (from the SBB website or any train station) to Kleine Scheidegg and back (no mountaintop views that way, but it is the most beautiful part of the trip). We also did Schilthorn and enjoyed that much more.
