Security told me that they let that lot empty first and then allow others. The advantage to this, after talking to security, is that Platnium drivers get the first out when the show ends. The gold lot is about 200 feet from the Platnium lot but the Platnium lot is the absolute closest. Both lots are seconds away from entry gate 6. Platnium ($100) and Gold (couldn’t find price) are immediately when you enter the venue property. The 3 levels of paid parking need a separate ticket (you buy on line and get mobile QR code).
Free parking comes with your ticket (not sure where this lot is). There are 3 paid choices Platnium, Gold and Premier Reserved. This post is in regards to information on parking - which I found very confusing on the venue website as well as Live Nation and other ticket sellers.
