Marriott Marquis San Diego Marina

Marriott Marquis San Diego Marina is the most convention-centric full-service hotel in downtown San Diego, a 1,360-room waterfront property directly connected to the San Diego Convention Center whose marina views, extensive meeting infrastructure, and Marriott Bonvoy terms have made it the most consistently booked large convention hotel in the market for citywide events and major corporate programs. The property's direct SDCC connectivity, marina setting, and the full Marriott Marquis brand infrastructure give planners the room block capacity, meeting flexibility, and loyalty currency to support the largest and most complex group programs in the city. For planners managing SDCC-anchored citywide conventions or large Marriott-preferred corporate programs, the Marriott Marquis Marina is the single most operationally logical choice in the San Diego convention hotel market.
