Marriott Marquis Marina

The 3rd biggest hotel in San Diego, a true landmark of the downtown waterfront scene, the Marriott Marquis San Diego Marina offers a complete resort-scale ecosystem for major conventions and large-scale business travel. With 1,360 guest rooms and suites distributed across two soaring towers, this property is one of the largest and most sought-after event destinations on the West Coast. Its sheer size is matched only by its incredible location, offering a private marina, expansive outdoor venues, and a direct, physical connection to the San Diego Convention Center.

This hotel is a self-contained convention powerhouse, built to manage the logistics of the most complex and demanding events. The property’s event infrastructure is colossal, featuring over 270,000 square feet of total function space. This is not just a collection of meeting rooms; it is a world-class event campus. The hotel provides two separate, massive, 35,000+ square-foot ballrooms: the Marriott Grand Ballroom and the San Diego Ballroom. This dual-ballroom design gives planners astounding flexibility, allowing for a general session in one and a trade show or elaborate meal function in the other, or for two major events to run concurrently without interference.

What truly separates this property from any other in the city is its unmatched outdoor event space. The hotel features the Marina Terrace, a sprawling 4.4-acre outdoor park-like venue that runs along the waterfront. This space can be configured for concerts, massive receptions, or creative team-building activities, offering a breathtaking backdrop of the marina and the Coronado Bridge. Additional outdoor venues, like the Coronado Terrace and the pool decks, provide more intimate settings for special events, all with spectacular bay views.

For convention attendees, the hotel’s convenience is absolute. A dedicated, covered skybridge connects the hotel’s second floor directly to the San Diego Convention Center. This seamless integration means attendees can move from their guest rooms to the main convention floor in minutes, without ever stepping outside or waiting for transportation. This proximity establishes the hotel as the unofficial headquarters for any major city-wide event.

Beyond its convention capabilities, the property is a true urban resort. Its name is not just for show; the hotel features its own private 446-slip marina, allowing for unique nautical-themed events or guest recreation. The central pool area is a tropical oasis, featuring two free-form swimming pools, whirlpools, and private cabanas, creating a vibrant social hub for guests to relax after a day of meetings. A state-of-the-art, two-level fitness center ensures wellness routines are not disrupted.

The 1,360 guest rooms and suites serve as tranquil retreats, with most featuring private balconies. These accommodations are thoughtfully designed for the modern professional, with dedicated workspaces and floor-to-ceiling windows that capture stunning, protected views of San Diego Bay, the city skyline, or the marina. The hotel’s two-tower layout (North and South) makes managing large, complex rooming lists and separating different groups straightforward for planners.

Dining at the Marriott Marquis is an experience in itself. The hotel is home to several distinct, high-quality restaurants. Marina Kitchen, the signature restaurant, offers modern American cuisine with a focus on local sourcing, while Roy’s Waterfront provides a high-end experience with its celebrated Hawaiian-fusion menu. For casual poolside dining and cocktails, the Tequila Bar & Grille is a popular spot. A full-service Starbucks in the lobby manages the morning rush, ensuring attendees can get a quick start to their day. This diverse collection of on-site dining keeps guests satisfied and allows for convenient client dinners or team meals.

The hotel’s location perfectly balances business and recreation. While attached to the convention center, it is also just a short walk from the vibrant nightlife and dining of the Gaslamp Quarter and the entertainment at Petco Park. This walkability makes it a prime choice for groups that want to experience the best of San Diego.
