The Windy City has a lot to offer travelers — especially those of the event planning variety. From modern digs to grand old dames, Chicago's hotels offer some of the most impressive meeting spaces and wedding venues in the country. Here we've collected our favorite ballrooms, which can host hundreds of bustling conventioneers or blushing brides with all of the necessary bells and whistles that make an event memorable. So get out your calendar, we're off to the Midwest to seal the deal! First up is the grand ballroom at the historic Hilton Chicago. At 1,544 rooms, the Hilton is a behemoth with a rich past (presidents and dignitaries have stayed here). It's extravagant lobby and this ballroom still impress, as do the faux old-world rooms that feature high-tech amenities. Public spaces fall a bit flat, but for event planners in search of a hotel with a storied past in the South Loop, you can't do much better.
