Sheraton Hotels has re-launched its website to emphasize user-generated content and take advantage of the popularity of social networking, writes DM News. Visitors can share stories, photos, travel tips and favorite destinations. The site will offer a "click to call" option for reaching a Sheraton employee, and also plans to offer live chat with the hotel.

To promote the new Sheraton.com, the company is giving away a vacation that includes five rooms for five nights at any Sheraton in the world, including roundtrip airfare for five, $5,000 in cash and five digital photos for recording the experience and sharing it with others.
