Midweek at the arena is far better for all the booths, swag bags, and secret shopping. Definitely don't just show up at the finals. The games are still high quality, but all the ancillary booths and such are far less lines in midweek. If its like last year, your two tickets will entitle you to a pair of swag bags that are big enough to be annoying to carry around all day, If you have a plan just snag your swag bags (both) one day, Grab the nalgene bottle if you're into free water in the arena and put the rest of the shit back at your hotel etc. I think the mega creep games in the last two ti's have been midweek days. Insane games to spectate live.
I'll be there wed-sun too.
