Here's all the maps for CES 2011 thrown about in a vague representation of the actual showfloor.
There are five maps in all, and those two side-by-side in the middle (South Hall) make a somewhat identical map on their reverse sides for the upper and lower levels.
I've failed to represent scale to ensure you get the size. I can easily say that I'm six-foot tall and I could comfortably lie down on these maps like a bed. And a human would definitely take up less space on the maps than a single character of the illegible printed text.
Yep, it's a big show.
