The logistical issues:
There was a huge bottleneck getting in. Lots of people struggled with Ticketmaster's NFC system. More readers and instructions ahead of getting to the readers would have helped.
The concessions line was long and the people processing it were slow / inefficient. They were very chatty and were mixing drinks on the spot. Fun I guess but I like efficiency
Rideshare pickup was bad because they made some weird design choices in the flow of how to get cars out (e.g., didn't have a free-flowing exit, cars with passengers could be bottlenecked by cars without passengers). We left during BD and got a car after about 20 minutes. I read on Reddit that others said to budget an hour. Drivers seemed to be avoiding it - we had two cancel on us.
