Hosting a Conference or Event in St Louis

Conference hotels in St Louis range from downtown properties near the Gateway Arch to venues with outdoor event spaces, and Engine lets you search, compare, and book them all. The Marriott St. Louis Grand leads the list with its Majestic Ballroom running about 20,000 square feet (capacity up to 1,990 people), 52 event spaces, and 917 guest rooms, making it one of the top options you can book through Engine for a large corporate meeting or multi-day event. Event planners, travel managers, and attendees booking their own rooms can find properties across the city with the meeting space and guest-room capacity they need.

Engine booking data shows June is St Louis's busiest month for business travel, with about 18% more room nights than the city's average month. If your event lands in June, book the room block early.

St Louis draws organizations of every size and industry for conferences, corporate events, and large meetings, from pharmaceutical and healthcare gatherings to trade shows and annual summits. The hotels on this list serve both planners hosting an event and teams attending one, with event spaces that can accommodate hundreds or even thousands of attendees. You can search, compare, and book guest rooms at these properties on Engine; for a stay of 9 or more rooms, Engine Groups handles the room-block booking, and for 8 or fewer you book self-serve. If you need meeting or event space, Engine Spaces is Engine's venue product where you can find and request space at over 40,000 venues.
