Rent a car with flexibility on number of days
Hi to all Rent a Car's experts.
When I've rented a car in the past I knew exactly how many days I needed it.
I'm travelling to Spain next week but I don't know yet how many days I need it. It's going to be at least 4 days and max 7 days. What should I do? To book for a week and then if needed to return it earlier (or I need a special kind of booking for this?) or to book for 4 days and then call each additional day I need it?
Thanks!
