EventSource, the Sausalito, Calif. — based dot-com featuring a substantial on-line site selection database and other event planning tools, has a new promotion to encourage contributions to the hotel reviews section of its Web site. For every hotel review submitted by an event planner, EventSource will donate $5 to the Ronald McDonald Care Mobile Program. Your experience can translate into dollars for educational and medical services for children with unmet healthcare needs.

The EventSource Web site allows users to search for reviews of specific properties or for all reviews submitted for hotels in a certain city. Users can drill down to select only reviews by planners in a particular industry (such as high tech/Internet or communications/utility) or with a particular kind of meeting (incentive, convention, trade show, etc.). To submit a property review and send $5 to the kids, visit www.eventsource.com.
