I need to go
1. from the U2 bus terminal (coming by bus from Prague) to Hotel & Palais Strudhof on Pasteurgasse 1, and
2. from the hotel to the Wien Meidling, and
3. from the hotel to the Opera House, and
4. from the hotel to Sudtirolerplatz near the corner of Laxenburger Strasse/Wiedner GurtelI.
I have already bought a 72-h Wien Karte on line. Would you please help me with directions?
