Summer Tourism in the U.S. How has tourism in the United States fared this summer? NPR's Robert Siegel finds out that it's been a mixed bag. On average the country is seeing a slight rise, about 2 percent to 3 percent, in occupancy rates. But many travelers have chosen to drive and not fly to their destinations, and they aren't spending much when they dine out. From Orlando to Mackinac Island to San Francisco, people describe how their market has fared this summer season. Included are interviews with Todd Pack of the Orlando Sentinel; Steve Platt of the Lake Placid- Essex County Visitors Bureau; Brad Jones with the Mackinac City Tourism Bureau; Bruce Brossman with Xanterra Parks and Resorts at the Grand Canyon; and David Bratton wih the San Francisco Convention and Visitors Bureau.
