Here's the list taken from www.oktoberfest.de, with my own comments about the tents. Others may view them differently
01 - Hippodrom - wahrlich "hip" - full of wankers, I just can't be arsed to go back.
02 - Armbrustschützen-Festhalle - Popular with locals, usually excellent atmosphere.
03 - Hofbräu-Festzelt - weltberühmt - stuffed with tourists, nothing to do with the traditional Wiesn at all.
04 - Hacker-Festzelt - der Himmel der Bayern - Probably the second best tent on the Wiesn, lots of locals, good atmosphere.
05 -
Schottenhamel - Tradition pur - Probably the best tent on the Wiesn but too many (local) 16 year olds, excellent atmosphere, great beer. Good food.
06 - Winzerer Fähndl - Ein Prosit der Gemütlichkeit - Sometimes dull (by Wiesn standards) but easier to get in for it.
07 - Schützen-Festzelt - unter den Augen der Bavaria - Popular with locals, usually excellent atmosphere, shame about the Löwenbräu.
08 -
Käfer's Wies'n-Schänke - Promitreff und Gourmet-Tempel - stuffed with tossers, again, but open an hour later.
09 - Weinzelt - Einen Wein in Ehren... WTF?
10 - Löwenbräu-Festhalle - Der Löwe weist den Weg - If you can stand the beer, and boredom, then it's OK I suppose. Have a laugh at the lion 'roaring' at the front.
11 - Bräurosl - echte Wiesntradition - Hosts Gay Sunday on the first weekend which is worth watching round the back of the tent later on, otherwise relatively easy to get in and good fun.
12 - Augustiner-Festhalle - familienfreundlich und gemütlich - Great if you're 90.
13 - Spatenbräu-Festhalle (Ochsenbraterei) - Ochsen aller Art - A good tent, easy(er) to get in. Good food.
14 - Fischer-Vroni - Wiesn für Fischliebhaber - Again, less popular with the herd, close to the U-bahn for staggering home.
(probably die of alcohol / chicken poisoning trying!)
I can't think of a better way to go...
