You have to show up at City Hall at the time specified (is it 9:00 a.m.? 9:30 a.m.?) on the voucher, to sign up for a tour. It is actually a little cart in front of City Hall manned by Guest Relations staff.
When there in March, we showed up at the time on the pass (9:00 a.m.? 9:30 a.m.?) and signed up for a tour which departed at 10:15 a.m. They give you a little pass and tell you where to meet at your assigned time.
Hope this helps.
