Best for adults who want a full casino resort experience with multiple bars, a spa, and resort-style pools.

Best for visitors who need a central downtown location for conventions, marina access, and a broad range of city-side amenities.
When Sycuan Casino Resort wins: Choose Sycuan if you want an adults-only getaway focused on gaming, poolside leisure with a lazy river and swim-up bars, a dedicated spa, and free self-parking. It’s the clearer pick if you plan to spend most of your time on property or nearby in East County.
When Marriott Marquis San Diego Marina wins: Choose the Marriott Marquis if you want to be in downtown San Diego near the marina, convention center, restaurants and museums. It’s better suited for business travelers, convention attendees, or anyone wanting easy access to Seaport Village, USS Midway, and the wider city.
Bottom line: Pick Sycuan for an adult-focused, casino-and-pool resort away from the city; pick Marriott Marquis San Diego Marina for a large, recognized downtown hotel with marina views and convention space. They serve very different travel needs—casino/resort vs downtown business/leisure—so your priorities (onsite gaming and pools vs downtown location) decide the choice.
