John Marks, president and CEO of the San Francisco Convention & Visitors Bureau, will retire on June 30, after 18 years as president of the bureau and 37 years in the tourism industry. Marks turns 65 in late May, though in a letter to members, he wrote that the decision was based not on his age, but on wanting to spend more time with his family. "I have no intention of remaining idle," he also wrote. "I plan to put my experience and contacts to good use, just not at a 60-hour-a-week pace."
