Marriott Mission Valley

San Diego Marriott Mission Valley offers the space, flow, and access that planners need for mid to large programs. With 350 guest rooms and suites in a clean, modern tower, the property keeps teams under one roof while staying close to Mission Valley retail, dining, and the San Diego Trolley for easy hops to Downtown, Old Town, and beach neighborhoods. Arrivals move smoothly from the front drive to a bright lobby, and elevators provide quick movement between guest floors and event levels.

Guest rooms are set up for multi-night comfort. Expect supportive beds, blackout window treatments, fast Wi-Fi, and ample outlets at the desk and bedside. Many categories add mini-fridges and expanded work surfaces so speakers, crew members, and attendees can reset between sessions. Quiet HVAC and sound-reducing windows help with early starts and late finishes.

Events are a core strength here. The ballroom handles general sessions and banquets, while a network of mid-size and smaller rooms converts quickly for workshops, speaker-ready spaces, sponsor lounges, and production offices. Corridor space along the meeting rooms works well for registration and coffee service, and service paths allow banquet teams to move efficiently behind the scenes. The in-house audiovisual partner provides a single point of contact for show calls, rigging, and rentals.

On-site dining keeps agendas on time. A full-service restaurant covers breakfast through dinner, a lobby lounge supports informal networking, and a café or market handles early call times and grab-and-go breaks. The banquet kitchen scales from plated dining to buffets and receptions, with clear labeling for dietary needs. Wellness stays accessible with a fitness center and a resort-style outdoor pool and patio for quick resets between blocks.
