Bargain 5: Romania
This eastern European nation is set to adopt the euro in 2012, but still uses the leu as its currency. In Conde Naste Traveler, Debra Klein writes that "In the meantime, the country is still eminently affordable."
She cites the example of Brasov, a well-preserved medieval town in the Transylvanian mountains.
Romania probably won't be the main target of your European trip. But if you're bound for Greece or Turkey, it could make a nice budget addition to your itinerary.
Bargain 6: The Baltic States
Here's the bad news upfront: Tourists have discovered the Baltic States of Lithuania, Latvia, and Estonia, and all of these currencies have made huge gains on the U.S. dollar.
The good news for dollar-toting Americans is that none of the Baltics has adopted the euro just yet. Outside of major cities like Vilnius or Riga, there are still bargains to be found and destinations worth seeing that are not overrun with tourists.
These are nations that enjoyed a high standard of living prior to Soviet occupation. They had highly developed economies, and they are struggling now to regain that prosperity.
As that transition takes place, it is still possible to find bargains, especially outside of the major cities. You are also likely to find people who are grateful for your visit, and perhaps willing to extend some added hospitality as a result.
