Traveling can be a way to gain life experiences，especially during Spring Break—a week long school vacation in the United States. But what if you're a student and don't have enough money for a trip？Don't worry. Here are some useful suggestions.

Save：This probably is the most important preparation for traveling. Cut expenses to fatten your wallet so you'll have more choices about where to go and how to get there.

Plan ahead：Don't wait until the last minute to plan your trip. Tickets may cost more when bought on short notice. Giving yourself several months to get ready can mean security and savings.

Do your homework：No matter where you go，research the places you will visit. Decide what to see. Travel books will provide information on the cheapest hotels and restaurants.

Plan sensibly：Write down what you expect to spend for food and hotels. Stick to your plan or you may not have enough money to cover everything.

Travel in groups：Find someone who is interested in visiting the same places. By traveling with others you can share costs and experiences.

Work as you go：Need more money to support your trip？Look for work in the places you visit.

Go off the beaten path：Tourist cities may be expensive. You may want to rethink your trip and go to a lesser­known area. Smaller towns can have many interesting activities and sights.

Pack necessary things：The most important things to take are not always clothes. Remember medicine in case you get sick and snacks in case you cannot find a cheap restaurant.

Use the Internet：The net can help to save money. Some useful websites include www.bargains­lowestfare.com_and_www.Economictravel.com.

By planning sensibly，even students can enjoy the travel. Your travel experiences will be remembered for a lifetime.
