If you are new to a co working space get a cup of coffee and walk around. Ask people about what they are working on. Then create potential customers for them
On the weekends, only the elevators in the center of the building will take you to floor 12. Instead, take any elevator to 13 (full of seasonal shops) and then take the stairs down to 12.
Only the "corporate" /center aisle elevators work on weekends/after hours. Look like a pro when leaving 1871 and walk past the first few aisles of elevators to the only ones that will take you down!
