The U.S. Open took place from July 31 to Aug. 8 last year. The researchers profiled 420 attendees to compile their data.
Officials at the three major downtown hotels — the Hyatt Regency Huntington Beach Resort and Spa, Hilton Waterfront Beach Resort and Shorebreak Hotel — said rooms were booked solid for the duration of the Open. Hyatt General Manager Cheryl Phelps likened the event to the Super Bowl in terms of public interest.
"It's really a five- to seven-day period when it's just great," she said.
Lt. Russell Reinhart said the Police Department would staff extra personnel during the Open, with as many as two sergeants and 20 officers assigned on the busiest days. Last year, he said, the event passed with no major incidents.
