When it comes to parking their car at the airport, many people are so focused on booking early and getting the cheapest price that they don't even bother to pay attention to the services and amenities. This has the potential for disaster, as some companies provide only good service or no service at all. You want to book with a reliable, reputable provider that keeps you and your vehicle's safety in mind at all times. This is especially true if you are leaving the country and need long-term parking.
The first and arguably most important service is that they must have a shuttle. Most long-term parking areas are not right on airport property. Instead, they are privately owned lots that may be across the street or from terminals down the street. In these cases, you should be able to park and catch the bus or shuttle at your terminal of choice. You can also go to www.parkonking.com.au/
There are fences around most of these lots, but fences alone are not enough to deter potential car thieves. Hence you should only go with the company which has additional safeguards to protect your vehicle. A car is too expensive to stand a chance. Some security measures that look good include cameras with remote monitoring and recording. Perhaps they even have round-the-clock security guards to stop the jumpers.
If you really want to get great and complete service in terms of amenities, then you can look for one of the car wash service providers. If you love a clean car, and hate getting into a dirty car, there are some that wash well and even offer interior cleaning like vacuuming and air fresheners.
If you travel frequently for business or pleasure, ask about discounts. Even with great amenities, some will offer you big discounts if you park often. Ask about loyalty clubs or wholesale discounts and see how much you can save.
