I need some logistic support, to make a perfect plan.

The point is that I am about ti go on Octoberfest with some my friends of mine from the old school dayz. We will go in the gang of 6-8 of us with rented driver.
What is my question. As far as I know Octoberfest is on the outskirts of Munchen. What I need for advice is where should I look for accommodation? What part of Munich? 5- 10 Km is fine. Any advice is very welcomed.
Is there any chances that I can meet some of you the during event?
Best regards,
Srdja (Darth)
