Best for travelers who want a mid-size downtown hotel steps from the Chicago Riverwalk and easy access to Millennium Park.

Best for large conferences, groups, and guests who need abundant meeting/banquet space in the heart of the river-area downtown.
When Royal Sonesta Chicago Downtown wins: choose Sonesta if you want a smaller downtown property directly adjacent to the Chicago Riverwalk, river-view dining, and a manageable boutique-ish scale with dedicated suites and easy walking access to the Magnificent Mile and Millennium Park.
When Hyatt Regency Chicago wins: pick Hyatt for very large meetings or events (tens of thousands of square feet of conference space), many on-site dining outlets, and a central location designed to handle high guest volume and convention logistics.
Bottom line: Sonesta is the better fit for travelers seeking a mid-size, riverwalk-focused stay with one prominent on-site restaurant and more intimate event venues; Hyatt is the practical choice for attendees or planners of large conventions or guests who want lots of on-site dining and meeting options.
