Travel Etc, 234 Merton Ave, Glen Ellyn, IL 60137, US

If it concerns hotels, cruise ships or anything to do with the travel industry, Northstar Travel Media is likely covering it. The company publishes a variety of magazines and indices that connect people on the retail side of things, like travel agents, with businesses, like Holiday Inn or Carnival Cruise Lines. The Glen Ellyn Office, says Research Supervisor Diane Swiss, is mainly responsible for what she calls "data maintenance," meaning that it provides content for such Northstar publications as the Official Cruise Guide and the Hotel and Travel Index Worldwide.
