Hyatt Regency O'Hare — Group Room Block, Meeting Space & Banquet FAQ
How much meeting space and how many guest rooms does Hyatt Regency O'Hare have?
Hyatt Regency O'Hare in Rosemont, IL features 1,096 guest rooms and suites alongside 100,000 sq. ft. of total indoor/outdoor meeting and convention space across 64 meeting rooms. Its largest ballroom spans 30,545 sq. ft., accommodating up to 3,215 attendees in theater seating or 2,263 for a plated banquet.
What is the true all-in nightly room rate at Hyatt Regency O'Hare during major conventions?
During peak 2026–2027 convention weeks in Chicago, standard last-room rack and OTA rates at Hyatt Regency O'Hare average $459/night plus a $25/night resort/destination fee and 17.4% local occupancy tax ($568/night all-in). By contracting a 10+ room block through the Conventions.com Housing Desk (Sara Chaval · (702) 576-1312), exhibitors lock a $269/night group rate with the $25/night resort fee waived ($316/night all-in — saving $252/room/night or 44%).
How do banquet F&B minimums and the '++' service charge work at Hyatt Regency O'Hare?
To waive ballroom rental fees at Hyatt Regency O'Hare, groups typically commit to a cumulative food and beverage (F&B) minimum starting around $42,000 for the main ballroom. All banquet food, beverage, and in-house AV orders are subject to a 25% banquet service charge plus 11.75% sales tax — creating an effective '+39.7%' ('++') multiplier. A $172/person plated dinner menu item therefore settles at ~$240/person all-in.
Can we bring our own independent AV production crew into Hyatt Regency O'Hare?
Yes, provided you negotiate out 'Outside AV Liaison & Patch Fees' prior to signing the hotel group sales agreement. While ceiling rigging points in the main ballroom remain under the exclusive jurisdiction of the in-house rigging provider, groups using ground-supported truss towers and our MasterMSA Production Addendum save 45%–62% compared to in-house AV rate cards.
