I don't think polygons for the crowd is a good idea either. I plan on using a texture (at least that's what Blender calls it) similar to this. It's just a bunch of jumbled up people.
BTW, I started a new thread for 3D stadium construction since we had kinda highjacked this one and are a bit off topic. You can post there if you want.
