I'm puzzled a bit about how best to book our train travel during our brief stay. We will be arriving at the Zurich airport at 8:30 in the morning on August 14, then traveling to Wengen via Luzern and Interlaken Ost. I know there is a direct train to Luzern that leaves the airport hourly at 47 minutes after the hour (I'm assuming we'd make the 9:47 train), but then there is a panoramic car with seat reservation options for the segment from Luzern to Interlaken.Then back to regular trains after that to Wengen. I realize that we can just travel the regular trains without seat reservations for the panoramic segment, but I will be traveling with my elderly parents whose dream is the scenic rail ride, so gimmicky or not, I want to get them seats in the panoramic car so they can best enjoy it.
We will be staying in Wengen for two nights (hopefully up to Jungfraubahn during our full day there) and then on our third day in Switzerland, we will be continuing on the Golden Express route on to Montreux and then on to the Geneva airport for a 19:30 flight that night.
My questions: How do I book this mixed itinerary that is part Golden Express on panoramic cars with seat assignments and part regular train? Should I just prebook the Golden Express segments now and get seat assignments but not the other segments? Or is there an advantage to doing them together? Does it make sense for us to get a transfer ticket or travel pass or half fare card or do those not apply to Golden Express bookings? I understand the routings involved, just not logistically how to best to book them.
And finally, in looking at the seat map, it's hard to know which seats will give my parents the best viewing on these routes. I'd appreciate any insight. Thanks!
