Figures come from the capacity chart in the hotel's 2025 Meeting Brochure. The brochure text describes groups of up to 675 attendees, and Cvent lists the Continental Ballroom at 675 theater and 500 banquet; the chart's figures are shown.
The chart calculates capacities with the Meeting Professionals International comfort calculator. U-shape figures are shown in the last column; the Executive Boardroom and Work Suite figures in that column are conference seating.
