You guys consistently went above and beyond

Dear (etr tour leader) Alan,

I just wanted to say thank you so much for a wonderful week in Greece! The kids had a great time, and it was mainly because of the effort that you, Eirini and "Magos the Bus Driver" put in throughout the week. You guys consistently went above and beyond the call of duty to ensure that our students had the best experience possible while in Greece. In fact, I cannot even imagine the trip without you, and hope that you would consider being our guide our trip next year as well! Thank you so much once again.
