Traveling is one of my favorite things to do but it can always be stressful. How wary are you of pickpockets? The world is rampant with them but I am especially wary when traveling to Europe.
I was once traveling with my husband's elderly grandfather and he had his wallet lifted off of him on the metro at the very beginning of the trip. He was devastated. His excitement for the trip quickly dampened and now he had no spending money for the trip. It really ruined his mood for the rest of vacation. He held back from any purchases as he felt he already lost the money despite us offering to buy it for him.
