Marriott Marquis

The San Francisco Marriott Marquis stands as one of the most significant large-scale hotels in the city, offering a massive inventory of 1,500 guest rooms. This property is an anchor of the SoMa district and functions as a self-contained “vertical convention center,” making it a premier destination for major national conferences, trade shows, expos, and large-scale corporate events. Its strategic location is a primary asset, offering direct access to the adjacent Moscone Convention Center and placing attendees within a short walk of Yerba Buena Gardens and Union Square.

For event planners, the hotel’s capacity is its greatest strength. The property features an immense amount of function space, with some sources noting over 133,000 square feet of total event space across approximately 60 individual meeting rooms. This vast collection of venues is anchored by the colossal 39,621-square-foot Yerba Buena Ballroom. This ballroom alone is engineered for high-production general sessions and grand galas, with the ability to host up to 5,500 guests for a reception, 4,380 in a theater-style arrangement, or 3,120 for a banquet. The event capabilities are further enhanced by a 22,563-square-foot Golden Gate Ballroom and over 23,000 square feet of dedicated exhibit space, ideal for trade show floors and sponsor showcases.

The hotel’s infrastructure is specifically designed for complex, high-density events. The event spaces are stacked vertically, allowing for streamlined attendee flow between general sessions, breakouts, and meals. Generous pre-function corridors provide ample room for registration desks, sponsor activations, and networking hubs without creating bottlenecks. Behind the scenes, the hotel is equipped with robust power distribution, rigging points for ambitious lighting and A/V, and practical freight access that allows production teams to flip rooms quickly and efficiently.

Managing an event of this scale, from booking hundreds of rooms to coordinating multiple vendors, is a significant operational challenge. This is precisely the kind of complexity Engine was built to solve. For operations managers tasked with booking a large crew or a block of conference attendees, our platform eliminates the chaos. Engine specializes in sourcing and managing group hotel bookings, with dedicated trip managers who can handle everything from sourcing and contract negotiation to managing rooming lists for 9,000+ travelers. We remove the administrative nightmare of booking large groups, so you can focus on the event itself.

The attendee experience at the Marriott Marquis extends well beyond the conference halls. Guests can unwind in the iconic 39th-floor View Lounge, which offers panoramic views of the city and bay. The hotel also features a 10,000-square-foot, bi-level COR Health & Fitness Center, the exclusive M Club, and multiple on-site dining options, including B55 Craft House & Kitchen and the quick-service Mission Street Pantry.

For finance teams and project managers, the true benefit of booking with Engine is the unparalleled cost control. Instead of drowning in spreadsheets and chasing contractors for receipts, our platform provides total financial clarity. You can track all travel expenses by project code, job number, or any custom field, ensuring 100% cost allocation accuracy. Furthermore, our Direct Bill feature solves major cash flow and reconciliation headaches. Engine can extend a line of credit to pay for all hotel bookings upfront, consolidating all charges from the entire event into a single, unified monthly invoice. This eliminates the need for credit card authorization forms and gives your finance team a clean, simple record of all event lodging costs.
