Where will Paul McCartney be staying when he plays at Wrigley Field in Chicago on July 31 & August 1 in 2011?

Paul McCartney will be performing at Wrigley Field in Chicago on July 31 & August 1, 2011 for his "On the Run" Tour and I will be attending his first show at the stadium. I am a young fan of his and the biggest thing that could happen in my life right now is the chance to meet or get an autograph from the famed Beatles and Wings frontman. Please don't think I just want the autograph to sell for money, because you would be worlds away from the truth. I would hold that autograph in such high regard. I would consider it gold. It would be my most prized possession, and I guarantee I will never let it go in my lifetime. It will be willed to my children and my children's children and their children after that. So if anyone has any information on where he might be staying at, and for how long, or if he will be making any public appearances anywhere in the city during his time here, I would greatly appreciate it. Thanks in advance.
