Having experienced normal DAH and seeing the disappointment regarding the crowds issue, that $145 dollars may just price me out of that if I were going during that time. IF they had Villainous Meet & Greets (be kind of cool to see them take over Fairy Tale Hall and give it a villainous overlay), then I would argue it's worth it. But with essentially only a specialized stage show with mixed reactions serving to spread out what seemed to have been an increased admission compared to a normal DAH, it doesn't seem worth that cost.
And I say this as someone who really loves Disney Villains (I've dressed as Gaston and Dr Facilier for past Halloweens). Who knows, I MIGHT try it depending on what they have for 2021. But right now, if I were going in 2020, it's a really tough sell.
