If all you want is a specific answer to the specific question then the answer is no, nothing is impossible. Highly unlikely in most cases...you personally may not have a snowball's chance in hell...etc, but it would not be true to say that "it is impossible to get reservations this late".
If you'd like to know whether or not it is possible for you to get a reservation this late then you need to enter into the discussion, deal with the banter, answer questions posed and hopefully tease out the answer relevant to your specific circumstances. Or you can just flounce off in a huff as you appear to have done with your "Never mind" comment.
You're so, so right. How foolish of me to think that people who LIVE in Munich would know whether the tents are indeed sold out already. And what a crazy idea to think that LOCALS would know how to procure a reservation if indeed the reservations are sold out at the breweries.
Answer the questions posted? What questions? I don't see any questions except my own. Banter? Is that what you call it? Like the person who thinks I do not have any business getting a reservation because I am a "tourist". What kind of nonsense is that? That is not banter. It is a telling-off.
We have been to Oktoberfest every year since our honeymoon. And yes, since we do not live in Germany, that makes us "tourists" (am I supposed to apologize?). We know that reservations are sold in lots of 10, we know that it is busier at night and on the weekends...I did not ask about any of those things. I did not request a primer on Oktoberfest.
I simply read on some old, old threads that the tents were sold out as of January or February and became alarmed.
We know the tent we want to visit and the times we want to be there...what we don't want is to wander around hoping someone will let us sit with them (as we have done in the past) and we don't want to leave at 3 or 4 in the afternoon because the rest of someone's table has arrived. We arrived at noon on a weekday last year and had a very hard time finding a place for 2 and we had to vacate at 4 when the reservation showed up. So, that is why we want our own reservation. Is it really that hard to comprehend?
I will now flounce off in a huff and call Augustiner myself to reserve my place, if there are any places left. We will give away the remaining tickets to some other tourists as we meet them.
Thank you all for your kind and insightful advice.
