There is, but that inevitable change is one of my biggest gripes with how Universal markets and operates the event.
The event’s quality is not the same opening weekend as it is mid-October. Really, the performances rarely start clicking until week 3 (hi, Blumhouse). Nearly every other haunt in the nation knows this and, as a result, gradually increases their admission costs the better their show gets (and the closer it gets to Halloween).
Universal ignores that. Opening night (which is still basically a rehearsal for the performers) costs the same as the last week when everything is quality. For guests, they’re paying more for less then.
