Oktobertfest tent Oct 5th... any tips? join? (Munich)

Hi,

I'll be running the Berlin Marathon and after that live the experience of the Oktoberfest on Oct 5th. I have been looking for options to get a place for a tent (Hacker Festhalle / Hacker-Pschorr, Schottenhamel, Winzerer Fähndl, Hofbräu, Festzelt, Marstall or any other) but it seems it's impossible. Any recommendation? It seems that you can go in a group and make it happen with an online reservation (we are two).

Is there a way to make a queue and make it to the tent?

I appreciate any recommendation and let me kb
