Phil Nash provided wise advice concerning the philosophy of travel study. Do not take 'off the shelf' itineraries. All the instructors try hard to customize each trip to reflect or expand upon the material covered in the Gentrain course.

We have had vintners, lawyers, doctors, musicians, artists, diplomats, dancers, hydrologists, and others whose expertise have significantly added to the value of the trip.
