In my previous position at Rider I would take hundreds of high school students visiting from Italy, Kazakhstan, Spain, Portugal, and other places on tour to New York City, Philadelphia, Washington DC, Los Angeles, San Diego, and San Francisco.  I was essentially a cruise director without the boat.  The students were visiting in the summer for two weeks where they would go to class for 3 hours in the morning and learn English.  The remaining 21 hours was up to the Study Tours Counselors to take them to various tourist attractions.
