It might still be salvageable, if you can find lodgings and arrangments in the general area for the correct week (obviously with the event going on, you might not be able to find prime locations anymore) and then ask the airbnb you accidentally booked if you can get a refund, explaining what happened and how stupid you feel. It depends on if the airbnb is operated by the owner, or a business. If its the owner they might let you off the hook, understanding how much of a devastating fuck-up it is.

I mean, I vaguely heard about that decades later, so doesn’t that mean they got away with it?

You should listen to the zero 7 - look up track if you haven’t already. Its very good.
