Before leaving I made a notebook with everything I needed to know -- who we were meeting up with, when, and where. What we should see in each city. In some cases, how we getting from Point A to Point B. It came in very handy. As we went on tours, I took notes while also taking pictures.
Our flight was delayed by several hours making it nearly impossible to catch up with the one person we were hoping to see while on our adventures: Susanne. Susanne was an exchange student with my parents while I was living in Belgium with the Rotary Club. We planned to meet up at 5 PM, but had to change that to 10 PM when our flight did not arrive until 8 PM. It was 4 PM New Jersey time, but remember we had an overnight flight, and a day of traveling. It was worth the lack of sleep.
