Sonesta Redondo Beach & Marina, at 300 North Harbor Drive on King Harbor, has a 7,500 sq ft Coral Ballroom for up to 1,000, the water-view Seascape Ballroom and a 6,556 sq ft Harbor Terrace over the marina. Above the Line provides audio, video and lighting for every room.
The hotel pairs a three-section ballroom and a block of breakout rooms with water-view spaces on the marina: the Seascape Ballroom, SOL, the Promenade and the Harbor Terrace. 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 capacity chart. Photos are the hotel's own, from its Cvent venue listing. Production notes describe a typical Above the Line setup for each space.
The hotel's largest room, with modern chandeliers and two foyers, dividing into Peninsula, Pacific and Redondo.
Reception 1,000 · Theater 900 · Banquet 550 · Classroom 400
For an 800-seat general session, we build a wide stage with a center LED wall or twin projection screens, hang speakers on ground-stacked truss and add camera positions on risers at the back.
A water-view ballroom with a planked-wood ceiling and French doors to a private patio.
Reception 320 · Banquet 220 · Theater 200 · Classroom 90
For a reception that spills onto the Seascape Patio, we zone the speakers so the patio can run at a lower level and add uplighting along the French doors.
A second-level terrace with views of the marina and the Pacific.
Reception 600 · Theater 550 · Banquet 450
For a sunset reception on the Harbor Terrace, we run weather-ready speakers along the rail, a wireless mic for toasts and warm uplighting on the palms after dark.
A stand-alone event space with an open-air veranda, fire pits and radiant heating.
Theater 120 · Banquet with dance floor 90 · Reception 70
For a private dinner in SOL, we add a compact speaker system with a wireless mic and pin-spot the tables, keeping gear clear of the fire pits.
A private room on the Promenade Level, mostly lined with windows overlooking the ocean and the marina.
Reception 175 · Banquet 100 · Theater 90 · Classroom 50
With an 8 ft ceiling in the Promenade, we use flat-panel displays rather than projection and add a pair of speakers on stands.
A boardroom with a granite-top conference table.
Banquet 14 · U-shape 14
For a hybrid board meeting, we add a camera bar, table mics and a display at the head of the table.
All figures come from the hotel's Meeting Room Capacity Chart.
