They said that after I change the reservation I can submit the two reservation numbers and they will reimburse the original reservation. The thing I find confusing is the upgrade ticket. Our plan was to purchase an 8 day Swiss pass when we arrive. I checked the the upgrade page on line and it says:
You can always decide spontaneously whether you would like to travel in 1st class, by purchasing a route-specific class upgrade online in the SBB Ticket Shop, using your smartphone with SBB Mobile, at the ticket machine or counter. For the class upgrade you will need a ticket, a 1-day travelpass or a GA travelcard for 2nd class.
It doesn't mention a multi day swiss pass. Do you know if it's possible to purchase the an upgrade for one day of a multi day Swiss pass?
