We are nearing the kickoff to the second annual Ace Comic Con in Glendale, AZ. The convention has recently updated its site with some useful info for attendees in regards to the layout of the con as well as some info on parking.
The map below gives you an idea where to find different areas of the con. It looks like they may have removed all vendors from the floor level which after last year, I am totally in favor of. The lines for photo ops and autographs on the floor level made it extremely difficult to navigate while trying to shop.
As far as parking goes, pre-purchase parking is NOT yet available at this time via the Gila River Arena website (the site does not list Ace as one of the events you can pre-purchase parking for) but here is the map that gives you an idea of how much parking is for events at the arena.
