To assist you in using public transportation, you will find a search engine available in German. Please consult the information under City Map. There you will find a list of all the meeting locations with addresses and also the link to the search engine. Please enter under "Ort" (location) the word "Wien" (Vienna). Click on "Str./Nr." (street/number) and enter the street and street number. Then you will receive the time schedule. Note that the subways regularly run about every 5 or 6 minutes, so there is usually no long delay.
