Request and offer vacant seats on reserved tables.
We’ve been running an Oktoberfest reservation exchange on Facebook since 2017. If you have spare seats on your reserved table, you can use this group to find people to join you. On the other hand, many users found reserved seats there on short notice. We chose to keep our group bilingual, as most reserved tables go to German-speakers, obviously. However, we want to emphasize that selling reservations is strictly prohibited. Asking people to buy the vouchers that come with each reserved seat, is not considered a sale, though.
Unfortunately, there is now a copycat with almost the same name and identical cover picture. This group was founded by scammers and serves the sole purpose of ripping off members. Despite several reports, Facebook has not yet deleted this group.
