For us, we had a lot of people wearing masks under their noses, several areas were very cramped, and we did see people wiping tables to try and keep up, but we also had to rewipe (we have always carried our own wipes) tables as there was food stuck, and I don't think it was all Knott's, it was just people being people. We were just uncomfortable. Friends we were with loved it.
Comparing Disney events, the Villains event listed as $145 (kids and adults) for a 10p-1am (6pm entry allowed) event, free parking. Yes, you had rides and entertainment, for more than twice the price.
