DoubleTree by Hilton Hotel Torrance - South Bay, at 21333 Hawthorne Boulevard, has 18,588 sq ft of event space across 11 rooms, led by the 5,292 sq ft Crystal Ballroom. Above the Line provides audio, video, lighting and LED for meetings, dinners and weddings across the hotel.
The hotel offers a boardroom, flexible function rooms and a penthouse-level ballroom with views of the South Bay. We size sound, video and lighting to each room from the hotel's own chart.
Room names, sizes and capacities come from the hotel's Events page at hilton.com. Photos are the hotel's own. Production notes describe a typical Above the Line setup for each space.
The hotel's largest room, for theater seating of up to 500 and dinners of up to 400.
Theater 500 · Banquet 400 · Reception 350 · Schoolroom 300
For a 400-guest dinner in the Crystal Ballroom, we set a stage and dance floor at one end, with two screens and a line of uplights along the windows.
A second large room for up to 200 at a banquet, reception or theater setup.
Theater 200 · Banquet 200 · Reception 200 · Schoolroom 120
For a 200-guest reception in the Penthouse, we keep the sound to a compact speaker pair and a wireless mic for toasts, with soft color on the walls.
Three salons for sessions of up to 225 theater style in Salon C.
Salon C: Theater 225 · Banquet 180 · Reception 120 · Schoolroom 120
For a 225-seat session in Salon C, we use a center screen and a lectern mic, with a second screen on the side so the back rows can read the slides.
A mid-size room for theater seating of up to 150.
Theater 150 · Banquet 100 · Reception 100 · Schoolroom 80 · U-shape 40
For a 40-seat U-shape workshop in Horizon, we put a projector and screen at the open end, with a speakerphone for remote presenters.
Garden Court, Emerald, Heritage and Jade, for meetings of up to 80.
Garden Court: Theater 80 · Banquet 75 · Emerald: Theater 45
For a breakout in Garden Court or Emerald, we use a 75-inch display on a stand and a small speaker, so the room resets quickly between sessions.
A board room for meetings of up to 10.
Conference 10 · Banquet 10
For a meeting in the Executive Board Room, we add a display with a conference camera bar, so remote attendees can join the table.
All figures come from the capacity chart on the hotel's Events page. The chart does not list room dimensions or ceiling heights.
