I have a short two day stay coming up in Berlin in June. I wanted to catch the Dark Worlds tour in English on a Monday since that's the only day they have it of the two days I'm there. Unfortunately, the tour is at 3 pm and I arrive at 1.30 pm into Berlin.
I've exchanged email with the team running Berliner Unterwelten to explore if i can pay in advance and pick up the ticket on arrival. That doesn't seem possible. Other than calling them after arrival to check if tickets are available before going over, any other suggestions on how I can buy the tickets in advance and pick them up on arrival? Is there something like taskrabbit.com in Berlin, perhaps?
