Watch out. There are hordes of kids and not so young fans camping out at these hotels and bugging the players for autographs, even in the wee hours of the morning. The players are good guys and they sign some autographs, but they usually can't get to them all. Especially the Wings. I've traveled with teams before and it's insane how some kids are waiting at the hotel at 2am for the bus to pull up.
That said, I only know that they stay at the Westin Michigan Avenue in Chicago and the Holiday Inn Suites in Kanata (Ottawa).
