The party was planned to be in Frankfurt, Germany.
As for interest, it was pretty high. There's another thread about that, I think linked in the OP.
Ente
Germany it was, and 220 reservations were made. A theoretical ~$220,000 buys a bloody big party!
Noticed the original plan was to refund everyone if no more than 100 tickets/reservations were obtained, so the interest was definitely there. I wonder if logic says that more interest will exist now??
