Hilton Tucson El Conquistador opened an 11,000-sq.-ft. Executive Conference Center in 2012. Designed for groups of 10 to 100, the center has eight meeting rooms, including a boardroom with a built-in 70-inch LED TV for presentations. Audiovisual equipment, worktables with built-in electrical outlets and energy-efficient lighting were also installed. Windows and balconies in the meeting rooms will offer sweeping views of the Catalina Mountains. The 428-room hotel has an additional 31,000 square feet of meeting space separate from the conference center.
