Taking a trip to another area in your country or elsewhere gives children the chance to learn about their world. Start your planning as far in advance as possible. You should choose somewhere to stay that best suits your family’s needs. For example, having a kitchenette will be useful for preparing some of your meals and keeping fresh food on hand. Keep in mind that laws and policies are different in different countries, including laws and policies for airlines, restaurants and food labeling.
