Currently the World Summit 2017 takes place in Berlin (tuesday to thursday).
Unfortunately I couldn't get a ticket (was too late) but I'm still very interested in visiting
the thursday sessions (e.g. Herb Sutter...).

Is someone of you currently "on-site" to get a clue if it would be possible to me to buy a ticket directly
in Berlin? Or is someone here who owns a ticket but can't go tomorrow and would sell it to me?

Any quick reply is welcome
