Exactly, Season 4 lends itself to be a house the EASIEST. Human sized villian, unlike the second house which had a huge mind flayer in. Much of their props that they probably still have from houses in previous years can easily be changed into Victor Creel house setting.
I’m not here to say that costuming would be easy for Vecna by any stretch. However, this season lends itself to be a house beautifully, from the inside Creel House, Eddies trailer, the upside down which they’ve already successfully created twice etc…
I’m not saying that I think it will happen, but IF it did, it would be the largest house in HHN history from the attendance and queue standpoint. It holds some records for Netflix’s viewing hours and appeals to younger and adult attendees.
