A friend and I are going to Allstate Arena in Rosemont soon for a boxing match and are staying at Holiday Inn Express. I read that the arena is only 2 or 3 blocks from hotel. Is it safe for us to walk to and from the arena to our hotel? It will be dark when we leave the boxing match and if it's a bad area, I will just drive and pay the $15 to park at the arena instead. thanks.
