As already said above, you’ll probably be the only ones with the exclusive privilege of reserved seats in an almost empty coach in the IC 6 between Bern and Visp.
The IC 81 between ZRH Airport and Bern might be slightly busier, as the last “batch” of commuters between eastern Switzerland and Bern will be on that train. But most of those “business” commuters traveling in 1st class (usually at company expense) are on the earlier trains.
NOTE: After boarding the train at the Airport, you might quite probably run into the slightly embarrassing situation that other people are already sitting on your reserved seats, so you’d need to chase them away.
Why you ask? Because reserving train seats is THAT uncommon in Switzerland (and possible only on some train types such as IC’s), we locals are simply not used to check whether a seat is actually reserved or not before sitting down, let alone checking seat numbers, let alone checking coach numbers… (“What? Coaches are NUMBERED??”)
