My wife and I will be traveling from Zurich to Salzburg on a Railjet train and decided to splurge 20 Euro total for 1st class, since it's a 5.5 hour trip. Reservations are not mandatory, but I wanted to ask the collective braintrust here if it is recommended - it's an additional 6 Euros total to get a reservation. I just don't know how crowded the train will be, or how likely it will be that we cannot sit together without a reservation.
Appreciate any and all thoughts on this...
Thanks,
Wade
