I'm not an expert on the Greensboro hotel accommodations, but I don't think there is anything near the Greensboro Coliseum. You'll have to drive to the game. There are plenty of parking lots on the grounds, plus many of the neighboring stores will rent you a parking spot as well. The closer to the GC you want to park, the more it will cost you, typically $10 to $20.
There are lots of hotels/motels on I-40, especially near the High Point Road exit. That's where the Koury Convention Center/Sheraton Hotel complex is http://www.hotelplanner.com/Hotels/4...vention-Center This is a reasonable area to stay in for going to the GC and there are restaurants and shopping around that exit.
Have fun, root hard, and help us raise another ACCT banner!
