If the above is not allowed to break journey in Vienna, then i guess 58 euro 1st class for all 4 to Budapest, specific booking from rail-jet again is the best option ? and use the Salzburg -budapest and get off in Vienna only,as its still cheaper than Salzburg to Vienna (1st class 1 person is 83 euro)
How is the second class for 7 hr journey with kids Budapest-Prague ? Do you get compartment type ?
With the prices you have quoted for budapest-prague 19 euro
As you said Einfach-Raus-Ticket for only 28 euro all day long in Austria..Can we use that to travel to zell am see or any other short trips from Salzburg with Einfach Ruas ticket ?
Also i cant find Rail jet option to prague ? does railjet option is there in vienna-prague route ? how are the EC/IC train on vienna-prague?
Will it be good enough if i go there early and occupy the seat.
