Studio 4 at W Sydney is a compact 34 m² hotel event room at 31 Wheat Road overlooking the Darling Harbour precinct. Marriott's room chart lists up to 20 for reception, 10 in conference or banquet settings and 9 in classroom configuration; it does not publish a theatre layout for this room. Studio 4 is best matched to intimate meetings, working groups and short breakout sessions rather than large presentations. It belongs to the hotel's level-five events inventory with on-site hospitality and production services; equipment hire and catering arrangements should be agreed with the events team for this specific studio.
