There are two main options:
SparSchiene Ungarn - "Limited allocation restricted to a specific train, no exchange, specific refund terms"
2nd class: 87 Euro (for 3 people)
1st class: 117 Euro
Standardpreis International - "Standard ticket not restricted to a specific train, full flexibility"
2nd class: 109.80 Euro
1st class: 174.60 Euro
Can anyone please explain the difference between the two main ticketing options.... and then the 2 separate classes? I assume 1st class is just nicer, but maybe it entails more than this.
I'll be booking this train for 3 people (myself included) to Buda from Vienna.
Thanks all!
