Hi, and welcome to MySwissAlps!
>> My boss will be traveling to Switzerland 10/10 through 10/16. He will be staying in Montreaux and has already booked a Panoramic Train Ride to Gstaad with continuation to Gruyeres on 10/13 and a tour of Berne on 10/14. He is interested in the VIP Golden Pass from Montreaux to Zermatt on 10/15.
Montreux to Zermatt is not the Golden Pass route, it's just a normal route from Montreux to Visp, then the Glacier Express route from Visp to Zermatt. You cannot board the Glacier Express at Visp, but you can take a regional train running along the same route Visp-Zermatt.
The Golden Pass route runs Montreux-Zweisimmen-Interlaken Ost-Luzern. The panoramic windows and VIP seats are on the sector Montreux-Zweisimmen.
>> Is the train ride to Gstaad/Gruyeres different enough from Zermatt to justify a 2nd train ride?
The trip Montreux-Gstaad is part of the Golden Pass route. If he wanted to book a VIP seat, this trip would have been the one on which to do so. There are still some VIP seats available on both the 9:44 and 15:44 departures from Montreux on 13 Oct. Only these two departures have the VIP seats.
The trip from Montreux to Zermatt is a completely different experience. Montreux to Visp is pleasant, but not outstanding. Visp to Zermatt is very scenic. Zermatt itself is wonderful.
>> Is there a VIP Golden Pass ticket available on 10/15?
Yes, there are currently 2 VIP seats left on the 15:44 departure from Montreux to Zweisimmen, but none on the 9:44 departure.

The sector Montreux-Gstaad is identical to his other trip. If he wanted to continue to Zweisimmen, there is plenty of lovely scenery along that sector too.
>> If so, does anyone know what that runs in US Dollars?
The reservation fee is CHF 15 for VIP seats. On top of that, you need a first-class ticket or pass. If he already has a second-class ticket or pass, he could buy an upgrade to first class just for that sector.
