My wife and I will be visiting Vienna for 8 days in early July, and we're planning to take 4 to 5 day trips. We'd like to keep our trip focused on Austria, cities and small countryside towns, rather than heading farther afield to Prague and Budapest (which likely deserve their own separate trips).
What are some of the best day trips from Vienna?
And should we buy individual tickets on ÖBB, or is an Eurail pass a better deal?
Ideally, we'd like to have options in terms of choosing travel days and times, and hopping on and off trains or buses during the day (e.g. Wachau valley). Does the Eurail pass allow for this? Or do we still need to reserve seats ahead of time and pay extra fees? It's not very clear to me which transportation options are covered with Eurail in Austria.
Thanks for your advice :)
