Anyone have experience booking suites in downtown Chicago? I'm helping plan my friend's bachelor's party, which will take place on the Friday of Memorial Day weekend. Probably looking at 20-30 guys, half of whom will inevitably wind up crashing on the floor, so the suite should be at least 700 square feet or so. I'm also hoping to keep the price below $500.

Any suggestions would be appreciated. I'm top-tier elite with both Hyatt and Starwood, but I don't think that will help me in this situation.
