Hello Spur365365
Please kindly note, the FIP rail pass cannot be used to purchase reduced day passes; it only grants 50% off on point-to-point tickets.
Thus, today, the full fare Saver Day Pass costs CHF 52 on the 14 January, same on the 17 January. That is the lowest possible fare for full fare tickets.
Seat reservations are not possible on your routing, it is free seating. Yes, the right hand side in travel direction is more scenic while the train goes along Lake Geneva (Lac Leman).
Kind regards,
Roland
