If there's one ticket that will be impacted this year... it's ROF. Universal has already enticed people to come earlier... and it's working very well.
September was busier than October last year. There was a pretty significant drop in attendance once ROF passes were finished last year. It was pretty incredible to visit HHN during what is typically the busiest weeks (the week leading up to Halloween) be a pleasant experience. Late October HHN nights felt like September from a few years ago.
The busiest weekend at HHN was in September... it was quite remarkable to see.
