The best mode of transport for you trip will depend on the country you are travelling to and the locations of the gardens you intend to visit - so it is important to plan your transportation before you set off.
A rented car is very convenient for visiting places country districts which are poorly served by other types of transport. One can also enjoy the peacefulness of empty roads. Though more expensive, the best plan is often to hire a car in one town and return it to an auto depot in another town. Generally it is cheaper to book the car before arriving in the destination country, though local car-hire firms can be cheaper than international auto rental firms.
