A buddy and I are backpacking Europe for 21 days with our first stop being in Vienna. (Budget is not an issue, he is meeting me coming from Croatia.) From 7 am the 29th of May till the 30th, we are in Vienna, then 31st are taking the train to Salzburg. We are in Salzburg from the 31st of May till June 2nd when we will head to Munich in the AM.
We already have itinerary forming, a lot of it from Rick Steves videos, but are curious for locations where to stay in Vienna location wise. Same goes for Salzburg on parts of the town where as walkers, we are closer to all the main sights.
The biggest question, is what 5 things should we do at all of the locations? Hitlers nest will be a trip in Salzburg for sure to get to the mountains, and a big part of history. (More of a cold war guy myself but when in rome i guess)
Also, on the way to Salzburg, are there stops worth getting off for a few hours or should we just get to Salzburg to knock that train ride out.
Appreciate any help and thank you!
