I use VIP valet. It's not the cheapest option, but in and out of parking is painless and fast, plus fastlane entrance to the venue itself makes it a no brainer for me.
Uber , or use heritage road to go around the back of the place , I did that last night and was out in 5 minutes.its longer but not as crowded.
If you like walking, do that, you'll be back to your hotel before people even move out of parking. Otherwise, Uber.
