San Diego Marriott Gaslamp Quarter anchors 660 K Street in downtown San Diego with 291 rooms, 15 suites, and 8,375 square feet of eighth-floor meeting space two blocks from the San Diego Convention Center. The property shares the K Street and Tenth Avenue intersection with the Gaslamp Quarter's densest concentration of convention-overflow hotels, including Hard Rock Hotel San Diego on Fifth Avenue, though the Marriott differentiates with a dedicated Soleil @K restaurant serving California-forward breakfast and a Latitude Lounge pouring local craft beer. Two ballrooms and five breakout rooms on the eighth floor convert into seven separate configurations, and an outdoor terrace accessible through the Presidio Ballroom accommodates standing receptions for up to 350 guests with a downtown skyline backdrop. The hotel sits adjacent to Petco Park, making it a primary booking target during Padres season alongside the Hilton San Diego Gaslamp Quarter one block east on L Street. Multi-day association conferences that split general sessions at the Convention Center and breakout programming across the Marriott's own eighth-floor footprint represent the property's highest-revenue event format.
