No we don't know...which is why I said it's a valid concern/worry. I can absolutely understand why someone would be concerned about this if they had already bought a
MNSSHP ticket expecting to be able to see certain characters and now not being sure which characters they'll see.
I'm not disagreeing that how it was run was poor. There's a huge pool of possibilities of how Disney could have addressed that between the madhouse it was and a paid special event. So yes, I agree that addressing the madhouse that it was is a positive effect, but if someone really wanted to meet those characters and can't afford another *higher* special event cost to see them and IF Disney limits access to those characters b/c of the new event, then I can see how it would not be a net positive result for others.
For me personally, it's a non issue. I'm not interested enough in the Villains to spend that much money to go see them, or to deal with the craziness of the meet and greet as it was before. Just because it doesn't affect me, or might affect me positively, doesn't mean I can't understand the concern/worry/dislike others may have, or that I can't have a general concern about the continued direction Disney's decisions are taking.
