I usually stay at the JW Marriott when in Chicago on business, but I'm not sure I can swing the $429 price tag for my next trip. Does anyone know if the Blackstone Renaissance has a Concierge Lounge and when it is open? The website mentions a thing called Hubbard Place Lounge but then doesn't say that there is a concierge level. Can I walk there from the Hyatt Center (71 S. Wacker)? Is it in a safe area of town?
