In the wake of the Sept. 11 terrorist attacks, many schools have shelved travel plans and canceled educational tours for their students. But educational travel company Explorica is working to change this trend with its unique use of the internet. Through the Explorica web site, parents can log into a personalized internet TourCenter to follow their child’s trip online. Tour directors, equipped with laptops and digital cameras, chronicle their group’s experiences, uploading photos and write-ups to the students’ Tour Diary on the Explorica site. According to the company, teachers who have returned from recent trips have indicated that parents have felt much more at ease knowing they could check on their child through the internet at any time. Explorica’s online tour-planning service includes the following destinations: Australia, Austria, Belgium, Costa Rica, Czech Republic, England, France, Germany, Greece, Hungary, Ireland, Italy, Liechtenstein, Mexico, Morocco, Netherlands, New Zealand, Portugal, Scotland, Switzerland, Turkey, and Wales. The company charges a fee for its services; for price estimates, users simply enter their ZIP codes and preferred destinations on the Explorica web site.
