If you are planning not to cover too much distance or to make use of excursions then it can be attractive to make use of transfers instead of a rental car. You will then be collected by a chauffeur and taken to the next destination.
Please ask us for this option if you are not sure about the difference in costs or if you prefer not to drive yourself.
If you stay at one location for multiple nights and do not need a car at this location, then it might even be cheaper to use transfers than to have a car. Of course you will always have more freedom to plan your own route when you have a rental car.
