I didn't get to Oktoberfest until around 17.00 on Sunday due to flight travels and was concerned I wouldn't be able to get a seat in my usual location in the Augustiner tent due to the very late arrival, it being opening weekend, my waiter/waitress not knowing I'd be there that day, etc. Anyhow, I was instantly seated by them making room and in fact had a choice of seats thanks to them. So seating shouldn't be an issue at all this year in the area
