I'm going to Oktoberfest this year 9/30 - 10/2 (30.9 - 2.10 for you Europeans) and I need information on purchasing tickets/reservations to sit in one of the beer tents. I need two for 30th and two for the 1st. I guess I'd like to know the easiest way for someone in the US to purchase tickets ahead of time without getting totally gouged. Any ideas? I'd especially like reservations for Augustiner.
