The hotels, convention center and transit systems are ready for the wave of Democratic Party delegates set to flood Denver starting this weekend. In fact, the Democratic National Convention isn't the biggest act Denver has seen or will see. "There might be a few more people on every flight, but we're not going to notice," said Denver International Airport spokesman Chuck Cannon. "We've had larger conventions. When the Shriners come, they bring 50,000 people," Cannon said. The DNC is expected to bring about that many people to Denver. And one week later — with a bigger economic impact — the Custom Electronic Design & Installation Annual Fall Expo comes to town.
