San Antonio Marriott Rivercenter

With 1,001 guest rooms and suites sitting directly on the San Antonio River Walk, the Marriott Rivercenter is the largest hotel in the city and a natural anchor for high-volume group travel. The property connects directly to Rivercenter Mall, which includes an IMAX theater, giving attendees and guests immediate access to shopping and entertainment without leaving the block. All 915 standard rooms and 86 suites were renovated as part of a top-to-bottom property refresh that also added new dining concepts and expanded the meeting floors. The hotel sits adjacent to the Henry B. González Convention Center, one of the country’s largest convention facilities at over 550,000 square feet of contiguous meeting space, making the Rivercenter an obvious room-block choice for major conventions spilling out of that venue.

The event facilities here span more than 70,000 square feet across three floors, a total reached after a renovation that added 11,000 square feet of new meeting space. The centerpiece is the Grand Ballroom on the third floor, covering 41,600 square feet with capacity for up to 6,400 reception guests, and divisible into salon rooms for breakouts. The second-floor expansion introduced the Pearl rooms, a trio of boardroom-style spaces that can be used separately or combined, plus the Southtown venue (three combinable rooms) and the King William room. In total, the hotel offers 45 redesigned event rooms and salon rooms, with 22 conference rooms on the third floor alone handling smaller sessions, pitches, and working groups.
