I have only been to two tents in the last two years .. meaning one each year.
I was in the Schwaben Braue tent last year, it was typical German "Fest" stuff Id say .. more hmmm the typical German good feelings music "Stimmungsmusik" and then I think they had Blues Brothers and Elvis stuff going on .. Germans are big on particular songs and you always hear them at these things (Wine Fests, Town Fests, Bierfest?
Er I mean the Wiesn/Wasen)
The Zum Wasenwirt tent was MUCH younger than the others, it was the SWR3 (thats a major regional radio channel) tent this year and has the reputation for being younger. I would stand by that, it was more people dancing on tables, more hot young girls in Dirndls and much more techno/dance type music mixed in of course with the usually drinking/Karnival songs (though here they are Fasching songs, there is no Karnival in the south).
Anyhow, yeah .. I didnt move around tents because its really hard to do, you either need reservations or have to be someone important, or I guess on a mission to see all the tents. However, since I live here, I figure that I will be around long enough to see all the tents eventually.
I think the Sonja Renz tent is more for groups of women going as a girls night out type of Wasen thing, but yeah at the Zum Wasenwirt the table next to us was also a group of college aged girls (alone) dancing on the table/benches in their dirndls .. so yeah thats about all I can say about that.
There were a few new tents this year, two more beer tents and a wine tent, as Stuttgart and the state of Baden-Wuerttemberg are wine areas. I know that for a fact because right behind my house are vineyards, I have steps that go up into them behind the house heh.
Okay like I said, as soon as the stores open again Ill post some pictures, hopefully that info helped.
However, there is no tent at the Wasen like Kaefer's tent/house in Muenchen.. which is almost exclusively for VIP/famous people
