I hope this helps everyone like it helped me. Here is what the amphitheater sent me by email when I asked about the options. The parking options from ticket resellers is across from the amphitheater but quite convenient and the exit speed is faster because you are not in the venue traffic jam. As people have posted here there is costly premier parking with faster entry and exit from shows and believe me it is worth it if you don't want to spend and got it more leaving after the show. Other apps like Stub Hub and Vivid Seats have different names for their parking options. The amphitheater has its own parking which you can find on their website or through Ticketmaster.
I was incredibly confused about parking outings at this venue.
