There are a few things to consider when choosing the best airport parking for your needs. First, make sure you have reserved parking. This will ensure you have a spot and avoid having to search for a space. 

Second, consider what you need the parking for. If you're only going to be at the airport for a short time, then self-park is probably fine. However, if you're planning on staying overnight, then it's worth it to reserve a space in Sydney airport parking.

 And finally, consider the price of parking. Some garages and lots cost more than others, but usually, it's worth it to pay a little bit extra for peace of mind.

When choosing airport parking, you should consider the cost, location, and convenience. 

The cost of airport parking can vary depending on the location and time of year. In some cases, you may be able to find cheaper parking near the airport terminal. If you're traveling during peak season, however, prices may increase. 

Location is also important when choosing airport parking. You'll want to find a spot that's close to the terminal entrance or your vehicle's departure gate. This will make getting to your car less daunting. 

Convenience is another factor to consider when selecting airport parking. Make sure the lot has easy access and is well-maintained. You also want to make sure your vehicle is secure in case you have to leave quickly.
