When looking for a car rental, it will soon becomes obvious that you are swamped with choice e.g) Enterprise car rental, Thrift car rental, Advantage car rental etc. A tip for narrowing your choice down is to start with a bulleted point list of criteria you must have. To begin with, first consider the rental car agreement; is there limited slots in which to pick up and drop off your car? Are you going to be under pressure if your plane is late for example, or maybe you are tired and just want to get off home on your return? Another question you should ask yourself is what if any excess is payable if the car is damaged; it may be worth paying the excess waiver insurance (it could be money well spent if an accident doe happen and you are in a foreign land and cannot speak to the local people).
