I think another pain point to put out there is the lack of entertainment in the queue lines. I know people have mentioned it ad nauseum at this point, but when you're in line for a house and all you get is generic HHN commercials, commercials for the other houses and advertisements for express and trivia, it's lazy and leads to a continued disjointed event. That is a quick and simple solution that could literally tie the whole event together.
But merch this year was very meh, tribute store this year was very meh, the event in general like I said before literally felt like marketing looking at numbers and spreadsheets and said "let's just do that." Lastly, HHN is absolutely missing the fun as well too. I know Bill and Ted is never coming back, but that mental break of being scared and then watching something to laugh really brought the event full circle.
