I was thrust into the role of tour guide this past weekend when chaperoning a group of 30 swimmers and parents to Athens for the 7th ACS Swim Gala at ACS Athens. It’s the kind of trip that is more challenging because we generally get around on public transportation and stay in hotels. Such an unstructured itinerary makes it more demanding on the trip leaders – similar, perhaps, to the challenges that Week Without Walls organizers face. I’m therefore sharing a few of the lessons I learned in the hope that others can learn from my experiences.
