Marriott Marquis San Diego Marina
San Diego, CA
Project Summary:
From 2010–2025, we have completed major renovations throughout the entire property, including softgood and casegood upgrades to 1,365 guestrooms, meeting space modernization, lobby and entrance improvements, kitchen renovations, elevator upgrades, a new 22,000 SF restaurant, and pool area enhancements. The PIP also added two 80,000 SF ballrooms, creating the 280,000 SF Marriott Hall expansion. Due to the success our team has had, we are grateful for the opportunity to continue renovating all of these spaces a second time over the next two years.
MA&A provided project management for the restoration of a historic Detroit landmark into a modern mobility and innovation hub. The work included stakeholder coordination, technology integration, and delivery of collaborative spaces and community amenities.
Over a 15-year partnership, MA&A has delivered extensive renovations across this flagship resort, modernizing 1,365 guestrooms, public spaces, dining venues, vertical transportation, and pool areas. The work also included a 280,000 SF ballroom expansion, with MA&A now leading a second round of renovations due to the success of earlier phases.
Over the past decade, MA&A has guided multiple major transformations at this five-star resort, including a comprehensive guestroom and public space renovation, a complete spa rebuild, athletic club expansion, and extensive meeting space upgrades. Current work includes new luxury villas and resort amenities, continuing MA&A’s long-term partnership in elevating the property’s guest experience.
