Hi, right now I think I am going to book a trip to these cities in late April - early May. I am looking at making it a 2 week trip so landing in Vienna Saturday 4/28 in the AM and flying out of Budapest Sunday May 13. My girlfriend is thinking about coming May 4-May 14 though so I am looking at what I can potentially do around Vienna before she arrives.
First I'm wondering is 3 days in each Vienna, Prague and Budapest enough? We would fly Vienna to Prague then Prague to Budapest to cut down on travel time. Or do you think we should cut the 9 days we're together to 2 cities (Vienna + 1 other) and do a couple day trips?
Second, what cities would you recommend visiting around Vienna during the 6 days I have alone? I don't really plan to base myself in Vienna the whole time so just looking for suggestions and reasonable destinations I could visit in the area. I am into architecture, food, history.
