As you travel throughout Vienna and Austria, you'll see signs with a fat "i" symbol. Most often that stands for "information," and you'll be directed to a local tourist office. Chances are the office staff can help you obtain maps of the area and even assist in finding a hotel, should you arrive without a reservation.
The sites for the Austrian National Tourist Office (www.austria-info.com), Vienna Tourist Board (www.info.wien.at), and Mozart Concerts (www.mozart.co.at) are good places to being your Web search.
