Nice! Where do you plan to go?
I always suggest Croatia to people, it is an increasingly popular destination in Medditerrannean Europe but significantly less expensive because it is not in the EU yet, and the standard prices in the local currency are less than EU countries. There are camps all along the coastline. There's also a camp in Patras, Greece, a cool and very clean place to kick it if you're passing through. Be sure to research, if you find yourself stranded in the middle of the night in a place that advertises camps but in fact has none, different countries will have different rules. While Greeks for instance will allow you to set shop anywhere you like, camp or no camp, the Croatians will have the police come....
Good luck
