If you are going on holiday and you need to travel around the foreign countryside, your best and most efficient option is, undoubtedly, to rent a car. However, this is not the only transportation strategy open to you and it is important to consider all possibilities before discounting them.
Depending on where you are staying and how far you will need to travel, you may be able to get away with renting a bicycle. This will work out to be considerably cheaper than it is to lease a Convertible for the Summer, however, it will also require a great deal more physical strain on your part.
Alternatively, you might consider travelling around by bus. This is not really an ideal solution if you are staying in a rural area since it will involve planning day trips in accordance with the bus timetable and this can be inconvenient.
Indeed, if you are not in an urban environment, it is probably best to rent a car to make day trips as easy and manageable as possible. Being in charge of your own vehicle will give you maximum independence to plan your holiday as you see fit, and it may even work out cheaper in the long run as well.
In short, there are several transport options open to you if you are looking to travel between destinations on your holiday. However, not every one is suitable for every situation: consider carefully before you make your choice.
