Delinquency is a serious problem in Mexico City. It is important to be aware of the dangers and take precautions so as to have a pleasant trip. As almost the world over, pickpockets are a plague for tourists. Leave your valuables in the hotel safe and do not carry around more money than is strictly necessary for your purchases that day. If you travel by car, avoid driving at night. Park your car in the hotel parking garage or in safe places. Do not leave anything out in sight inside the car.
