Good stuff!
A buddy of mine moved to Lisbon and I went over there for a trip a couple of years ago. Rented a bike and drove for 2 weeks circling the whole country (coast, mountains, etc.). Portugal was fantastic! Not only was it the best ride I have ever done, I think I spent less for 2 weeks food (fantastic) and lodging (decent) than I did on the plane fare! Beware the gas prices though

Many destinations in my own country (US) would have cost me more to explore.
Highly recomended!
