10 Best Hotels & Resorts in St. Louis, Missouri for Corporate Events (2026)

For an association annual meeting, the hotel decision comes down to a question most planners ask too late: can attendees walk from their room to the general session without crossing a street, and if not, what’s the shuttle plan? I’ve convened a three-day policy conference where the host saved money on the room block by splitting it across two properties, then spent the savings twice over on shuttles and lost the hallway conversations that make a convening worth attending. One roof matters more than the rate. Decide that first.

Hotels and resorts fit corporate events because the whole event lives in one building: sleeping rooms, general session, breakouts, catering, and a loading dock used to handling groups. For a multi-day conference or a sales kickoff drawing out-of-town attendees, that integration is the reason to choose a hotel over a standalone venue. St. Louis runs from downtown convention-corridor hotels to a Four Seasons on the riverfront. The ten below are ordered by review depth, with the room-block and meeting-space notes I’d put in the brief.

River City Casino Hotel

River City Casino Hotel on River City Casino Boulevard in south county holds a 4.1 across 9,851 reviews, the deepest review base on this list. It’s a casino-hotel with an event center, which puts meeting space, lodging, dining, and parking under one ownership, with infrastructure built for volume.

Figure several hundred in the event center, with an on-site room block. The casino-grade operation handles parking, security, and crowds as routine, and the integrated lodging removes the shuttle question entirely. The south-county location is away from downtown, which suits a self-contained event better than a city-center one. Best for a large company social, an awards night, or a conference where the integrated event center and the room block carry the logistics.

Hyatt Regency St. Louis at The Arch

The Hyatt Regency at The Arch on Chestnut Street downtown runs a 4.2 across 7,344 reviews. It’s a full-service downtown hotel beside the Gateway Arch grounds, with substantial meeting space and a deep room inventory, plus an Arch-adjacent location that does real work for an out-of-town crowd.

Plan for 300 to 600 in the larger function space, with a downtown room block. The location next to the Arch and near America’s Center makes it a natural headquarters hotel for a downtown conference. Confirm the meeting-space-to-room-block ratio, the F&B minimum, and the attrition terms. Book the Hyatt Regency at The Arch for an association annual meeting, a multi-day conference, or a sales kickoff where a downtown landmark location and a deep block both matter.

Hilton St. Louis at the Ballpark

The Hilton St. Louis at the Ballpark on South Broadway downtown holds a 4.0 across 5,747 reviews. It’s a full-service hotel next to Busch Stadium, which pairs convention-corridor meeting space with a ballpark-adjacent location, useful for a conference that wants a built-in evening option.

Figure 200 to 450 in the meeting space, with a downtown block. The stadium-adjacent location is the differentiator: a conference can build a ballpark evening into the agenda without arranging transport. Confirm the block cutoff and the attrition clause. Best for a downtown conference, a sales meeting, or an event where proximity to the ballpark and the convention center adds to the program.

Marriott St. Louis Grand

The Marriott St. Louis Grand on Washington Avenue downtown carries a 4.2 across 4,250 reviews. It’s a large full-service downtown hotel with extensive meeting and ballroom space, positioned in the downtown loft and convention corridor, a workhorse property for a larger convening.

Plan for 300 to 600 in the grand ballroom, with breakouts in the meeting rooms. The extensive function space handles a multi-track conference, and the Washington Avenue location is central to the downtown hotels and the convention complex. Confirm the meeting-space layout, the room block, and the F&B minimum. Best for a large multi-day conference, an association meeting, or a sales kickoff that needs a big ballroom and a deep breakout count downtown.

Renaissance St. Louis Airport Hotel

The Renaissance St. Louis Airport Hotel on Natural Bridge Road runs a 4.1 across 3,058 reviews, near Lambert airport. It’s a full-service airport hotel with meeting space, which suits a fly-in conference where minimizing travel time from the gate to the general session is the priority.

Figure 200 to 400 in the meeting space, with an airport-adjacent block. The airport location is the practical win for a national event: attendees land, shuttle minutes to the hotel, and never touch downtown traffic. Confirm the meeting-space inventory and the airport-shuttle arrangement. Best for a fly-in national conference, a regional meeting drawing air travelers, or a sales kickoff where airport proximity beats a downtown address.

The Royal Sonesta Chase Park Plaza St. Louis

The Royal Sonesta Chase Park Plaza on Kingshighway Boulevard in the Central West End holds a 4.5 across 3,043 reviews. It’s a restored historic luxury hotel, which combines landmark character with full-service meeting infrastructure in the upscale Central West End, a setting that reads as refined rather than generic.

Plan for 200 to 400 in the historic ballroom. The restored grand spaces are the differentiator: you get landmark character with the room block and catering of a luxury full-service hotel, no outside catering needed. The Central West End location is walkable and upscale. Confirm the F&B minimum and the block terms. Book the Royal Sonesta Chase Park Plaza for a leadership conference, a gala, or an event where you want a hotel with real architectural and neighborhood weight.

Marriott St. Louis Airport

The Marriott St. Louis Airport on Pear Tree Lane carries a 4.0 across 2,994 reviews, also near Lambert. It’s a second full-service airport hotel with meeting space, which gives a fly-in event another option in the airport cluster, with the same minimize-travel-time logic.

Figure 200 to 400 in the meeting space, with an airport block. As with the Renaissance, the airport location removes the downtown-traffic variable for a national crowd. Confirm the meeting-space layout and the shuttle. Best for a fly-in conference, a regional training program, or a multi-day meeting where attendees arrive by air and want the hotel steps from the terminal.

Moonrise Hotel

The Moonrise Hotel on Delmar Boulevard in the Delmar Loop runs a 4.5 across 2,628 reviews. It’s a boutique hotel with a rooftop and event space in the Delmar Loop entertainment district, smaller and more design-forward than the full-service towers, which suits a smaller, higher-touch event.

Plan for 75 to 175 in the event spaces, including a rooftop. A boutique property with a rooftop is the right scale for a leadership offsite or a smaller reception where design and a distinctive space matter more than ballroom capacity. The Delmar Loop location handles the evenings. Confirm the rooftop-event terms and the meeting-room AV. Best for a small executive offsite, a boutique client reception, or a leadership meeting where a distinctive space beats scale.

The Westin St. Louis

The Westin St. Louis on Spruce Street downtown holds a 4.2 across 2,286 reviews, in the Cupples Station historic district near the ballpark. It’s a full-service hotel in a converted historic warehouse complex, which pairs convention-corridor meeting space with downtown character and a ballpark-adjacent location.

Figure 150 to 350 in the meeting space, with a downtown block. The converted-warehouse setting gives the property more character than a standard tower, and the location is central to the downtown hotels and the ballpark. Confirm the meeting-space inventory and the attrition terms. Best for a downtown conference, a mid-size meeting, or an event that wants historic character with full-service hotel infrastructure.

Four Seasons Hotel St. Louis

The Four Seasons Hotel St. Louis on North 2nd Street downtown carries a 4.6 across 2,280 reviews, the highest rating among the high-volume hotels here. It’s the luxury anchor on the riverfront at the Lumiere complex, which combines top-tier finish and service with full-service meeting and ballroom space.

Plan for 150 to 350 in the ballroom. The luxury finish and riverfront location are the differentiators: a board retreat or an executive conference where the property’s quality is part of the message. The per-room and F&B reflect the tier, which an executive audience expects. Confirm the meeting-space layout and the block terms. Best for an executive conference, a board retreat, or a high-end event where the Four Seasons name and riverfront setting do the work.

How to choose among them

Start with the one-roof question, not the rate. Pull the meeting-space-to-room-block ratio on every proposal, because a property where attendees walk from bed to general session is worth more than a cheaper rate split across two hotels with a shuttle bill. Then read the attrition clause and the cutoff date, the terms that turn a good rate bad when attendance comes in soft. Last, match the location to the arrival pattern: airport hotels for a fly-in crowd, downtown convention-corridor properties for a city-center conference, the Four Seasons or Chase Park Plaza for an executive audience where finish matters.
