It just so happens that I'll be in Vienna when Oktoberfest starts. Does anyone have any experiences, is it worth it to go? We'd most likely go during the day, so we won't have to deal with tickets.
UPDATE: I'm asking about the "Oktoberfest" celebration in Vienna, not Munich. I apologize for not being clear.
UPDATE 2: We attended the Kaiser Wieswn on opening day - it was a total blast. We found a table in the Gösser tent and enjoyed beer, food, and song. If you're in Vienna during this time, I highly recommend it. Free during the day, admission charged in the evenings due to entertainment.
