Hyatt Regency St. Louis at The Arch

Hyatt Regency St. Louis at The Arch is a full-service hotel and event property in downtown St. Louis, situated directly adjacent to the Gateway Arch. The property offers more than 83,000 square feet of meeting and event space across two dozen distinct venues — anchored by the 20,000-square-foot Grand Ballroom, divisible into eight sections with a 14,600-square-foot pre-function area, and the 16,800-square-foot Regency Ballroom, which can be configured into six sections for more focused gatherings. High above the city on the 18th floor, the Gateway spaces combine indoor ballroom areas with an open-air rooftop terrace featuring an illuminated dance floor and views of the Arch — suited to ceremonies, cocktail receptions, and outdoor celebrations. An in-house culinary and catering team crafts event menus from locally sourced, seasonal ingredients.
