12. If you plan on attending any 18+ events, get your wristband earlier in the day

As it nears time for the 18+ late night showings/panels to start, everyone rushes to get a wristband and suddenly there's is a crazy long line. During the rest of the day there is no line for wristbands at all, so why not get yours earlier in the afternoon, then you can shake your head at the poor bastards waiting in yet another pointless line as you stroll into the event.
