Safety tips are important when you plan a vacation at a traditionally urban city like Chicago. Dangers include beggars and scam artists on streets. Apart from that you need to be in the right neighborhoods, find a hotel with good security measures, and take care of your car when you leave it in public parking spaces. Chicago's history with crime might seem old and distant, but the rules still apply.
Chicago's weather is also something to protect you from. If you are not going in summers, a good set of warm inners, a jacket and woolens can be necessary, especially in winter. Temperatures start dipping below 50 well before winter, and late summers can be an ideal time to start thinking about jackets for the locals. Make sure your health does not degrade due to the weather you are supposed to enjoy.
Chicago is a city with small neighborhoods. Types of people, the look of alleys change frequently and make for one of the most threatening scenes for singular travelers at nights. If you are planning to enjoy Chicago's nightlife in the Harbor area, it will be mandatory for you to avail transport, especially if you are not staying on any of the beach hotels.
Chicago has a fair bit of allergic content in the air, especially when the temperatures really start falling in early October. Ozone depletion is common in the summers, which can make for a crucial set of items such as sunglasses, sun protective creams and other things to make a part of your packing list.
