Going to Vienna later in the year for a couple of days. Any suggestions what to see/visit in such a short time. Also, where is the main "nightlife! area?
The Schonbrunn Palace is lovely, you can easily get there on the train, 10 mins or so away from city centre. About 3 mins walk from the station, lovely grounds and good audio guided tours available.
Wouldn't bother with the Reisengrad (ferris wheel) in Prater Park unless you want to be very nostalgic. It doesn't feel very safe.
