oh no i actually disagree strongly, in my opinion they need the hype and the momentum of Halloween very strongly. they need it for advertising and promotion and people looking for something scary to do, sure this is year long but they need a big opening,
also they could promote this when they promote the regular hhn and promote it together, remind everyone about it.
also, there have been some years when hhn orlando ended on november and the park is dead, people just move on once october 31st ends
