With the summer on the horizon, many of us are getting excited about a long, overdue vacation. Only one problem: travel is becoming ridiculously expensive. With oil prices way up and the dollar way down, where do you go without breaking the bank? Here are four great options for the traveler on a budget:

1) Eastern Europe-Prague, Budapest, Kiev, Bucharest. So much to choose from, and at a fraction of the cost of London or Paris. The eastern european capitals are both fascinating destinations and incredible values. They offer incredible histories, unbelievable architecture and wonderful people to the open minded traveler. In recent years, eastern europe has become increasingly popular, and Prague has become a tremendous tourist destination. The other countries are attracting more visitors as well. Just get on over in the next few years before they become too Westernized. For even better pricing, try visiting in the late fall. The prices drop even further but the weather is still manageable. Forget the winter. I've been in Kiev in January, and you can understand how the cold could literally stop an army.

2) Take a Carribean Cruise-If you don't mind the Carribean in the summer, the values are just fantastic. Many people wait until the colder weather to visit the islands, so prices plummet during the summer months. If you are looking for fun in the sun, just stick to five to seven days. For a more educational experience, check out the Panama Canal itinerary. Available ships leave out of several ports including Miami, Fort Lauderdale, Jacksonville and New Orleans. Couple of tips: book your excursions through the cruise ship. Yes, they are somewhat more expensive this way. However, in the event a tour is running late, the cruise line will hold the ship for you. If you take a tour on your own and something goes wrong, well, you're on your own.

3) Visit a National Park-the Smokey Mountains in Tennessee offer a tremendous value. A cabin in the park that sleeps six can be had for $ 120 per night. Lots to do including Dollywood, horseback riding, hiking, helicopter tours and more. The park is one of the top tourist destinations in the U.S., and one of the least expensive. The people are friendly and the food is great. Just remember to put your garbage away at night. Don't want any oversized critters ruining your vacation!

4) Costa Rica-I never worry what time of year it is for Costa Rica. They have two seasons, rainy and more rainy. Still, it doesn't matter. Between the people, food, wildlife, volcanos, eco-adventures and price tag, this destination is very tough to beat. You can fly direct from the United States into either Liberia or San Jose. Rent a car and just explore. The country is amazing and fairly safe. Watch your passport and belongings, but beyond that crime is minor. Great for the more adventurous traveler. Check out the ziplines, rappeling and much more.
