Convention Hotel with Vast Ballroom Space and Direct Convention Center Access

Hyatt Regency O'Hare is a major Rosemont convention hotel with roughly 110,000 square feet of event space and direct access to the nearby convention center. Ballrooms, meeting rooms, breakout areas, and supporting spaces give the property the scale and variety required for very large programs. The hotel can accommodate events numbering into the thousands while still providing smaller rooms for focused meetings, meals, or private sessions. Guest accommodations are in the same property, making the hotel especially useful for conventions and conferences with attendees arriving from around the country or staying for several days. Direct convention-center access makes the hotel especially useful as an extension of a major trade show or conference, with receptions, meetings, and guest accommodations immediately connected to the larger program.

Capacity reaches roughly 5,300 guests in the largest configurations, giving Hyatt Regency O'Hare the ability to support conventions, corporate conferences, weddings, receptions, galas, trade events, and major meetings. On-site catering, seating, Wi-Fi, restrooms, dedicated event coordination, audiovisual support, and extensive meeting infrastructure provide a complete foundation for complex programs. A convention can keep general sessions, breakouts, meals, sponsor activity, and networking within connected spaces, while a large gala or wedding can use ballroom areas for a more formal schedule. Direct convention-center access further expands the usefulness of the property for major events. The hotel is strongest when the event has many moving parts and needs large rooms, smaller supporting spaces, accommodations, food service, and technology to operate together. For a high-attendance program near O'Hare, the concentration of event infrastructure is one of the property’s clearest advantages. The breadth of room sizes also lets organizers keep executive meetings or smaller dinners appropriately intimate even when thousands of attendees are using the property elsewhere.
