Yes, the AAA area gets you a bit closer, but not all that much.
BUT......AAA has now changed their parking passes. They are dated, with the name of the person using them. Previous parking passes from AAA did say that they were not for sale and were non-transferrable. But, people didn't much care. They sold them on eBay when they were done with them. Some people even made copies of them and sold those. AAA seems to have closed that loophole.
Some AAA offices will give them to their customers even if they haven't bought anything from the office for their trip. Other offices (most common) say that you have to at least purchase park passes from them, and some offices won't give you the parking pass unless you book an entire package through them.
It is a perk, offered to AAA members. So, anyone using one that they are not legally entitled to should be prepared to be turned away.
