Educating yourself on where you are going is paramount. It is important to research the country's current issues so you know what you may be getting yourself into. The website http://travel.state.gov is a good first source of information about regions considered dangerous to Americans. Here you will find the latest travel warnings and alerts. In addition, there are Consular Information Sheets for every country. These sheets include information on the location of the US embassy or consulate, health conditions, areas of instability, political disturbances, as well as crime and security information. It is also important to research the culture of the countries you are going to. It is common courtesy to be aware of what is considered polite and appropriate versus what may be rude and disrespectful. Educating yourself on the culture can make for a smooth and easier transition into a new country.
As college students, a travel agent is not really in the budget when it comes to booking a trip. As an alternative, I would recommend visiting Barnes and Noble or a local bookstore like to buy books and gather information on your destination. Barnes and Noble has an entire section dedicated to traveling with books and maps titled by country. Endless amounts of information regarding dining, lodging, excursions, site seeing, history and so much more are right at your fingertips!
Another site that you may want to visit is the http://www.nationsonline.org/. This site provides a wealth of advice for the world traveler, including information on each country's government, culture, business, and tourism.
Happy researching!
