It's a hot ticket for a cold place. Every year, hundreds of the world's business and political leaders converge on the Swiss ski resort of Davos for the annual meeting of the World Economic Forum. And no, it's not only a place to see and be seen.The exclusive, invitation-only gathering tries to shape the global agenda for the year ahead during five days of nonstop meetings, sessions, plenaries, receptions, lunches and dinners. The business is as serious as the celebrity spotting (previous draws have included Angelina Jolie and Richard Gere; Bono is a regular fixture.) Last year, the main topic was climate change; this year more than 2,500 delegates from 88 countries will focus on a theme entitled "The Power of Collaborative Innovation." But they'll talk about other things too.
