what possible use would a suica card be at comiket, cause there arent that many things at tokyo big sight that use them, and with most transportation methods to get home, you still have to wait in line to get on, even if you have a ticket already.

though I am just nitpicking at this point. >.> <.<

You really want a Suica to get there. The line to get on the Rinkai/Yurikamome is nowhere near as bad as the line for the ticket machines.
