Best for historic character, rooftop views, and lively nightspots.

Best for larger suite layouts, a familiar brand experience, and direct access to Michigan Avenue shopping.
When Chicago Athletic Association wins: pick it if you want a historic building with multiple distinct dining and drinking venues (Cindy’s rooftop, Midōsuji omakase, Game Room, The Ives) and a more adults-oriented, social atmosphere.
When Omni Chicago Hotel wins: choose Omni for roomy, all-suite accommodation on the Magnificent Mile, straightforward meeting and conference space, and a location that’s very convenient for designer shopping and museum visits north of the Loop.
Bottom line: both hotels put you in central Chicago — go Chicago Athletic Association for characterful dining and event spaces in a landmark building, or Omni Chicago Hotel for predictable all-suite comfort and a prime shopping-district address.
