Return different location & drive cross borders

 When doing my trip planning I can be creative on that as a lot of places allow me to drive cross borders or let me return the car to a different location. 

Of course most often (not all the time depending on location) it comes with an additional fee which raises your car rental cost. That fee will be dynamic as different return locations and cross borders have different fees by different suppliers.

You see the exact fee during the rental car booking process.
