Please clarify about the train tickets on https://westbahn.at/en. It seems is OK to buy tickets on the train and not in advance since you cannot buy for a particular day or time on the web. We want to leave from Vienna to Salzburg on Friday May 4th morning and return the next day afternoon/evening. It is reasonable to expect to have seats at any time?
The OEBB trains are more expensive and you need to make reservation for a particular train/hour. Are there any better? More chances for a seat?????
PS For particular OEBB times on Friday you can get some cheaper tickets, but not on Saturday.
Is this a special weekend and we should made advance reservations? How long in advance?
