Kansas City Marriott Downtown — Group Room Block, Meeting Space & Banquet FAQ
How much meeting space and how many guest rooms does Kansas City Marriott Downtown have?
Kansas City Marriott Downtown in Kansas City, MO features 983 guest rooms and suites alongside 67,817 sq. ft. of total indoor/outdoor meeting and convention space across 25 meeting rooms. Its largest ballroom spans 15,080 sq. ft., accommodating up to 1,587 attendees in theater seating or 1,117 for a plated banquet.
What is the true all-in nightly room rate at Kansas City Marriott Downtown during major conventions?
During peak 2026–2027 convention weeks in Kansas City, standard last-room rack and OTA rates at Kansas City Marriott Downtown average $389/night plus a $30/night resort/destination fee and 14.5% local occupancy tax ($480/night all-in). By contracting a 10+ room block through the Conventions.com Housing Desk (Sara Chaval · (702) 576-1312), exhibitors lock a $239/night group rate with the $30/night resort fee waived ($274/night all-in — saving $206/room/night or 43%).
How do banquet F&B minimums and the '++' service charge work at Kansas City Marriott Downtown?
To waive ballroom rental fees at Kansas City Marriott Downtown, groups typically commit to a cumulative food and beverage (F&B) minimum starting around $28,000 for the main ballroom. All banquet food, beverage, and in-house AV orders are subject to a 24% banquet service charge plus 8% sales tax — creating an effective '+33.9%' ('++') multiplier. A $148/person plated dinner menu item therefore settles at ~$198/person all-in.
Can we bring our own independent AV production crew into Kansas City Marriott Downtown?
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.
