I am hoping to rent a car in Santorini in March and then again in Bolzano in June, and I'm not exactly sure where to start. I usually take trains and busses, but I feel like I'm ready to push myself and explore more deeply with a car.
For both, I'm hoping to pick up and drop off from the airport. Do I just search on Expedia or Kayak and make reservations that way, or is there a specific rental service I should be looking at? It took me a while before I learned never to book airline tickets through third party, so I don't want to have to learn a similar difficult lesson about rental cars.
I know I need an international drivers' license. Is there anything else I need to keep in mind?
Thanks in advance for any advice or tips!
