Actually, if you look at the interactive map, it looks like if you access LOS from the street, you come in on level 2.  Follow the white arrows and you'll walk down the first level through the stadium seats to get to the main floor.

It kind on looks like we'll be able to sit in the seats on the lowest level, like we did back in the old mecca basketball arena

GAH!  Why do all the Gen Con maps have South at the top?  Are you all from Australia or something?

Compare

Very confusing.
 

After 14 Gen Cons in Indy, it'd be confusing if they changed now....
