Seeking tips for a European Road Trip Hi everyone! Looking to get some idea of how driving thru Europe will be this Spring. My buddies and I plan to drive to Paris from either Spain, Germany, or Italy (still trying to decide). So a few questions,

* How are car rentals in Europe? Anything out of the ordinary?
* Is driving thru countries pretty hassle free? And what kind of tolls would we encounter?
* Any suggestions on small towns in France leading up to Paris (from the south side)? 

We'll have about 3 full days  after we are done doing some other stuff... any other tips or recommendations are welcome!
